Short answer: Ask the merchant to cancel the subscription and refund the charge. If the charge is unauthorized, appeared after you canceled, or is otherwise wrong, send a separate written billing-error dispute to your credit-card issuer. For a U.S. credit card, the issuer generally must receive that notice within 60 days after the first statement containing the error was sent.

An email to the merchant creates a useful record, but it doesn't automatically satisfy the notice requirement for your card issuer. These steps are for U.S. consumers and mainly cover credit cards. Debit cards, ACH withdrawals, bank transfers, prepaid cards, and payment apps can have different rules and deadlines.

Start with the payment method and the problem

The right next step depends on both. A recurring payment may also appear under a parent company or payment processor instead of the brand name you remember, so check the statement descriptor, receipt, and subscription settings before calling a charge fraud.

Deleting an app doesn't necessarily cancel the subscription. If you subscribed through an app store or wallet, the merchant may not be the party that can stop future billing.

The U.S. credit-card deadline

For the federal credit-card billing-error process, written notice must reach the issuer within 60 days after the first statement with the error was sent. The FTC's guidance on using credit cards and disputing charges describes the process.

The issuer generally must:

• Acknowledge the dispute in writing within 30 days, unless it resolves the problem sooner.
• Investigate and resolve it within two billing cycles, and no later than 90 days after receiving the dispute.
• Let you withhold the disputed amount and related finance or other charges during the investigation when the dispute qualifies under the billing-error process.

Pay the rest of the bill on time. The 60-day period is based on when the first statement was sent and when the issuer receives your notice. It isn't extended merely because you emailed the merchant or are waiting for a promised refund.

Many issuers offer a secure message or online dispute form. Others require a letter. Follow the instructions on your statement or the issuer's dispute page. If you mail a letter, use the billing-dispute or billing-inquiries address, not the general address for payments.

Gather the details before you write

A short, accurate timeline is more useful than a long accusation. Before sending either message:

1. Confirm the transaction. Note the merchant descriptor, charge date, amount, last four digits of the card, and date the first statement showing the charge was sent.
2. Describe the problem accurately. It may be an unrecognized transaction, a post-cancellation charge, a price mismatch, a duplicate charge, or an unexpected trial renewal.
3. Cancel the subscription separately. Use the merchant account, app store, or payment platform where you enrolled. Don't assume that disputing one charge stops future billing.
4. Save the record. Keep the receipt, subscription terms, renewal notice, cancellation confirmation, screenshots, support tickets, refund request, and issuer case number.
5. Limit personal information. Never email your full card number, security code, password, or Social Security number. Send identity documents only through the issuer's secure channel.
6. Send the issuer notice in time. If the 60-day period is nearly over, don't wait for the merchant's response.

Email template: cancel the subscription and request a refund

Use this for a direct request to the merchant. Replace the bracketed text and delete any sentence that isn't true. Don't include your full card number.

Subject: Cancel subscription and review charge dated [date]

Hello [Merchant Support Team],

Please cancel my [subscription or plan] and review the charge of [$amount] posted on [date].

Account details:
- Account email or customer ID: [email or ID]
- Statement descriptor: [descriptor]
- Card ending in: [last four digits]
- Transaction or invoice number: [number]

Reason for my request:
[Choose one: I canceled the subscription on [date] through [website or app], but I was charged afterward. / I do not recognize or authorize this charge. / The amount charged was [$amount], but my receipt or agreement showed [$correct amount]. / The trial or renewal terms were not clear to me.]

Please:
1. Stop future recurring charges.
2. Refund [$amount] to the original payment method.
3. Confirm the cancellation date, refund date, and refund reference number.

I have attached [cancellation confirmation, receipt, statement excerpt, or other proof]. Please contact me through this email address or ticket.

Thank you,

[Account email]

The merchant may deny the request under its terms, offer a partial credit, or ask for more information. Keep the reply either way. It may help establish what happened if you later contact the issuer.

Written credit-card dispute template

Send this to the card issuer, not just the merchant. Use it as a secure message only if the issuer says that channel counts as written notice. Otherwise, send a letter to the issuer's designated billing-dispute address.

Subject: Written dispute of credit-card billing error: [merchant] [amount]

Dear Billing Disputes Team,

I am writing to dispute a billing error on my credit-card account. Please treat this as written notice of the disputed transaction.

Transaction details:
- Merchant or statement descriptor: [name]
- Transaction date: [date]
- Amount: [$amount]
- Card ending in: [last four digits]
- Date the first statement containing the charge was sent: [date]
- Transaction or invoice number: [number]

The charge is a billing error because:
[Explain the facts briefly. For example: I canceled the recurring subscription on [date] through [method], and the merchant sent confirmation [number]. The charge posted afterward.]

I contacted the merchant on [date] and received [no response, a refusal, or the attached response].

Please investigate, credit the disputed amount, remove any related finance charges if applicable, and correct my account. Please confirm receipt of this notice and provide the result of your investigation in writing.

Attached are copies of [statement excerpt, receipt, cancellation confirmation, renewal terms, and merchant correspondence]. I have not included my full card number or security code.

Sincerely,

[Full name]
[Billing address on the account]
[Phone number]
[Email address]

Keep a copy of the message or letter, every attachment, the delivery confirmation, and the date the issuer received it. If the issuer says you used the wrong department or channel, resend the notice promptly through the required method and keep both records.

If the recurring charge is truly unrecognized

Check the statement descriptor, your subscription accounts, and whether another authorized user made the purchase first. A renewal you forgot to cancel isn't automatically an unauthorized charge.

If you genuinely don't recognize the transaction, call the issuer before relying on email. The issuer can tell you how to protect the account, whether it needs a written declaration, and whether it recommends replacing the card.

Subject: Unrecognized recurring charge dated [date]

Hello [Card Issuer or Fraud Team],

I do not recognize or authorize the recurring charge of [$amount] from [statement descriptor] posted on [date] to my card ending in [last four digits].

Please open an unauthorized-transaction investigation and tell me what steps are required to protect my account from additional charges. I contacted the merchant on [date], if applicable, and [describe the response or state that there was no response].

Please confirm my case number, any required written declaration, and whether you recommend replacing the card or taking other security steps.

I can provide supporting information through your secure channel.

Sincerely,

[Full name]
[Billing address]
[Phone number]

If you knowingly enrolled but didn't realize the renewal date, describe it as an unexpected renewal. If the price, disclosure, or cancellation record is the problem, explain those facts instead of claiming that no authorization existed.

A shorter message for a charge after cancellation

This version is for the merchant when the key issue is timing. If the issuer's 60-day period is approaching, send the separate issuer dispute as well.

Subject: Dispute of subscription renewal after cancellation

Hello [Merchant Support Team],

I canceled [subscription or plan] on [date] through [cancellation method]. Your confirmation number was [number], but a charge of [$amount] appeared on [date].

Please stop all future recurring billing and refund this post-cancellation charge to the original payment method. Confirm the account's cancellation status and provide the refund reference when processed.

Attached are the cancellation confirmation and statement excerpt.

Thank you,

[Full name]
[Account email or customer ID]

For a trial conversion or price mismatch, ask the merchant to identify the renewal disclosure and the price shown at signup. That is more precise than calling a charge fraudulent when you did sign up but disagree with how the renewal occurred.

Evidence that can help

Put the files in date order. The most useful evidence is usually:

• The statement page showing the merchant descriptor, amount, and date.
• The original receipt, order confirmation, or subscription agreement.
• The renewal notice and the price displayed before renewal.
• Cancellation screenshots, confirmation emails, and ticket numbers.
• Your refund request and the merchant's response.
• Proof of when and how the issuer received your written dispute.
• A brief timeline containing only the relevant facts.

Redact the full card number and unrelated transactions. Keep the original files in case the issuer needs a clearer copy.

A refund, billing dispute, and chargeback aren't the same thing

• Merchant refund: The merchant voluntarily credits the payment method. Its policy and the facts of the transaction affect the result.
• Credit-card billing dispute: You tell the issuer that a qualifying billing error occurred. This is the process tied to the federal written-notice deadline.
• Chargeback: The issuer and card network use their own process to reverse or challenge a card transaction. Network reason codes and deadlines may differ from the federal billing-error process.

A merchant refund may be the quickest solution to a simple mistake, but requesting one shouldn't make you miss the issuer's deadline. Blocking a payment or replacing a card also doesn't necessarily cancel the underlying subscription, so cancel it separately.

If the merchant says it issued a refund, ask for the amount, processing date, original payment method, and refund reference. Once the credit posts, notify the issuer if a dispute is still open so the account isn't credited twice.

What happens after you send the issuer notice

Merchant refund timing and posting times vary. The credit-card deadlines below concern the issuer's handling of a qualifying billing error, not a voluntary refund from the merchant:

• Within 60 days of the first statement being sent: The issuer should receive your written notice.
• Within 30 days after receipt: The issuer generally acknowledges the dispute unless it has already resolved it.
• Within two billing cycles, and no later than 90 days: The issuer investigates and resolves the dispute under the FTC-described process.
• While the investigation is pending: Pay undisputed charges and keep the account current.

These timelines aren't a universal deadline for debit-card disputes or every network chargeback. File as soon as you notice the problem and follow the issuer's instructions.

If the merchant or issuer denies the claim

When the merchant refuses the refund or doesn't respond:

1. Save the refusal or your unanswered request.
2. Send the written dispute to the issuer before the deadline.
3. Attach the cancellation record, terms, receipts, and communication history.
4. Watch the account for additional recurring charges.

If the issuer denies the dispute, request the written reason and the documents it relied on. Look for an appeal deadline. Then answer the specific factual problem in the decision. For example, if the issuer treated the subscription as active, send the cancellation confirmation and explain the dates.

For a possible scam or compromised card, call the issuer using the number on the card, change compromised account passwords, and review recent transactions. You can also report suspected deceptive conduct through the FTC's contact guidance. A report may help regulators identify patterns, but you still need to use the issuer's dispute process to seek a card-account correction.

Mistakes that can cost time

• Sending only a merchant email and assuming the issuer's deadline is preserved.
• Waiting for the merchant while the 60-day credit-card period runs out.
• Labeling a renewal as fraud when you knowingly enrolled and simply forgot to cancel.
• Refusing to pay the entire credit-card bill instead of paying undisputed charges.
• Sharing your full card number, security code, or password with support staff.
• Assuming that deleting an app canceled its subscription.
• Relying on a promised refund without checking that the credit posted.
• Applying U.S. credit-card deadlines to a debit, ACH, or bank-transfer dispute.

This is U.S.-focused consumer information, not legal advice. State subscription laws, card agreements, and procedures for non-credit-card payments may change the available options. The FTC's billing-error guidance is another reference for the federal credit-card process. Check the statement, cancel billing where you subscribed, and send the issuer's notice through its approved channel before the deadline.
