A card transaction is in progress or has been validated on your account? You don't agree with this payment and would like to refuse it?
If the transaction has been refused by the merchant but appears to be in progress on your account, go here.
If the fraud is not of your making, please block your card as soon as possible and follow the steps listed here.
In the event of a dispute with a merchant you know, we suggest that you first contact the merchant to find an amicable solution. It is not technically possible to refuse a transaction in progress. However, the merchant may reimburse you if the transaction was unnecessary.
If this is unsuccessful, we invite you to contact us, enclosing the e-mail exchanges you have had with the merchant.
