By law, you have a "cool-down period" of two calendar days, within which you can terminate the consumer credit agreement for any reason. This applies to both personal loans and credit limit.
You simply need to repay the full amount of credit received with the app, within two days, counting from the day you signed the consumer credit agreement.
As for the credit limit - if you decided to cancel it later, then you should firstly pay the used credit limit balance.
In all cases please chat to us. Please note: simply removing or deleting the credit card from the app is not enough!
