Complaint Handling

Upon receipt of a complaint, the complainant will receive an acknowledgement of receipt and the complaint will be processed promptly. Since each complaint is individual, must be examined and requires the necessary research, the final result, depending on the complexity of the matter, will be communicated to the complainant verbally and/or in writing within fifteen working days.
We strive to find a fair and satisfactory solution. If the complaint takes longer to resolve, the complainant will be informed of the reasons for the delay and the expected response time. The final answer must under no circumstances be later than 35 working days after receipt of the complaint.
How do we deal with customer complaints?
Customer satisfaction is our top priority!
All complaints submitted to our bank are recorded in an electronic environment.
Depending on the content of the complaint, our Service Center Team will initiate the necessary steps. If necessary, information is obtained from other Departments / Branches to ensure quick clarification.
You can get information about the status of your complaint by calling our Service Center Team.
For all completed complaints, you will receive feedback according to your preferred communication channel (email/phone/letter).
If we are unable to meet your demands on us entirely, we will explain our position to you in detail and demonstrate ways of maintaining your complaint.



The handling of complaints is free. There is always the possibility to direct a complaint to other bodies:
