Schocking service

We are a small homeowners assocation for a complex with 6 free standing houses. We have had an account with Absa for over 25 years where we pay our levies and then pay relevant expenses like security garden services etc. For the past year Absa have been locking our account every few weeks due to FICA requirements which we had submitted in 2022. So I have had to go into the branch every time to sort out. Then they open it for a week and then it is frozen again. I have now been submitting new documents for the last month still no account. I am so sick and tired of ABSA they are the worst bank ever with no rush to resolve any matters. Client managers come and go and no one commit to get issues sorted which means wr have no access to our money. Really!!!!!!!! What do one have to do to get this issue resolved?
