Why it happens
- The amount was keyed in wrongly.
- A price was changed after the cardholder agreed to it.
- Extra charges were added without the cardholder’s agreement.
Visa12.5Processing error
Incorrect Amount
The cardholder was charged an amount different from the one they agreed to or the one on their receipt.
What to send to fight it
- The receipt, invoice or checkout record showing the amount the cardholder agreed to.
- The cardholder’s agreement to any additional charges.
- Proof a partial refund already covered the difference.
How to prevent it
- Show the final amount, taxes included, before the cardholder pays.
- Get written agreement before adding any charge after the sale.
