The lender must inform you of cancelling your right to use credit
Most credit contracts contain a clause under which the lender may cancel the consumer’s right to use continuous credit. This means that the lender may block your right to use a credit card, for instance.
The justification for cancelling a consumer’s the right to use credit must be in keeping with good lending practice. Acceptable reasons include suspicions of unauthorised or fraudulent use of the credit.
The lender must inform you in advance of cancelling your right to use credit and the reasons for it in a permanent form (in writing or electronically). If the lender has to cancel your right to use credit at once, for example to prevent misuse or damage, they can inform you of the cancellation afterwards. However, the lender must inform you without delay.
If your right to use continuous credit is cancelled, you have to repay the credit you have taken out on the terms set out in the credit contract.
