Well, that’s frustrating. Here are a few reasons why you may have been charged on the wrong card:
Amazon purchases
Amazon charges you when they dispatch your item(s), rather than when you placed your order. That means that you will be charged on the card that is selected in-app at the time of dispatch.
In the event that the wrong card is charged, you can use Go Back in Time to change the card you paid on to another card in your Curve app.
Offline transactions
Some merchants will occasionally process your purchases "offline" – these merchants are typically: hotels, airlines, Japanese retailers and American restaurants (when tipping). Transport for London (TfL) will often also send through "offline" transactions.
Some merchants send an authorisation at the time you present your card. Then, they let it expire and then send a separate “offline” transaction a few days later.
This can show as 2 (or more) charges on your account. However, don’t worry, in these cases, you’ll only be charged by Curve once.
Go Back in Time
