What Is a Chargeback Dispute? Basics and Key Differences from Refunds
A chargeback dispute occurs when a customer contacts their card issuer to reverse a transaction due to issues like non-delivery, fraud, or defective goods. The issuer temporarily credits the customer and debits the merchant's account. Merchants can then file a representment (counter-dispute) with evidence to fight it.
Unlike refunds--direct reversals initiated by merchants--chargebacks bypass the seller, involving banks and networks like Visa or Mastercard. Consumer rights under Regulation E (U.S.) and similar global laws make chargebacks eligible for unauthorized/fraudulent charges, non-receipt, or service not as described.

| Cons | Slower resolution; dispute fees if lost; credit impact | Merchant controls; may deny valid claims |
| Time | 60-120 days total | 1-30 days |
| Cost | Free for customer; $15-100 for merchant | Usually free |
