Complaining about transactions
Paying with your credit card is secure. We nevertheless recommend you check your billing. If you do not agree with a charge, please contact the merchant first. If this does not help, you can complain about the payment online.
If you have made a travel or flight reservation on an online platform and have not received confirmation for this, then please contact the provider before rebooking.
Do you want to complain about interest or fees that are listed on your statements under the heading "Miscellaneous"? Please contact our customer service by phone or in writing.
If you are affected by recurring fees (subscription costs), the following list of contacts for the most common merchants might assist you in canceling your subscription.
