How do I dispute a transaction?

If you were incorrectly charged by a merchant or something else is wrong with a transaction (such as the time or amount), we suggest contacting the merchant first. If the merchant does not collect the money, the transaction will automatically reverse after eight days. If a merchant has already collected the money (i.e. the transaction is settled) we'll need evidence that you have contacted the merchant and tried to resolve the situation before we can dispute the transaction for you.
