Why it happens
- The merchant is enrolled in the program.
- The disputed charge falls within the program’s rules.
American ExpressFR6Fraud
Partial Immediate Chargeback Program
The merchant is in the Partial Immediate Chargeback Program, so some disputes, usually low-value ones, are charged back without an inquiry first.
What to send to fight it
- Proof the merchant was not in the program when the charge was disputed.
- Proof a refund for the charge was already issued.
- Records showing the charge falls outside the program’s rules.
How to prevent it
- Resolve complaints and refund quickly, since there is no inquiry stage for these charges.
- Keep clear records of every refund issued.
