If the bank does not deliver in accordance with your contract, you can complain. This can, for example, be unauthorised withdrawals from your account, wrongful interest calculation or if the bank fails to advise you against a bad financial deal.
First, you must send a written complaint to the bank. You can use The Consumer Council’s (Forbrukerrådet) complaint letters.
If the case is not solved after your written complaint, you can contact the Norwegian Financial Services Complaints Board (Finansklagenemda). The secretariat of the board will give you both oral and written advice and can help you further with your complaint.
