Understanding Credit Card Charge Disputes and Your Consumer Rights

Credit card disputes are informal complaints to your issuer about errors. Chargebacks are formal reversals where the issuer pulls funds from the merchant. The FCBA (Fair Credit Billing Act) mandates issuers investigate billing errors, unauthorized charges, and goods/services disputes.

In 2025, U.S. consumers reported $12 billion in unauthorized charges (FTC data)--up 15% yearly. You have strong rights: Issuers must acknowledge disputes in 30 days max and resolve in two billing cycles (typically 90 days).

Mini case study: Sarah spotted a $500 unauthorized charge. She reported within 48 hours, filed a police report, and used her bank's app. Funds reversed in 45 days--no liability.

Valid Reasons for Credit Card Chargebacks

Common grounds include:

• Fraud/unauthorized charges: Criminal use (long tail: credit card fraud dispute).
• Non-delivery/not as described: Goods never arrived or were defective.
• Billing errors: Double charges, wrong amounts, math errors (credit card billing error complaint process).
• Failed services: Subscriptions canceled but billed.
• ATM disputes or international issues.

Visa/Mastercard rules align but use reason codes (e.g., Visa 10.4 for fraud). Valid reasons ensure 75% approval if evidenced.

Consumer Rights Under FCBA for Unauthorized Charges

FCBA limits your liability to $50 (often $0 if reported before use). For fraud, report ASAP--no strict deadline, but 120 days ideal. CFPB reports 85% win rate for timely unauthorized claims. Protections apply to open-end credit like cards, not debit.
