Account Frozen with zero notification

Our business bank account has been frozen for outstanding FICA documentation. All documentation was supp**** to Standard Bank on the 13th September last year as part of our KYC review and we received an acknowledgement of receipt from the bank. We were not asked to provide further documentation nor were we contacted by our business banker to request the proof of address or regarding the imminent freeze. Plus, the supposed outstanding documents were part of the September submission. On top of that, we supp**** our documents last week Friday and are now expected to attend a teams meeting this Friday. It's been over a week and the lack of service, when we have had our business bank account for over 20 years with them, is unacceptable. Our branch closed over 3 years ago and we were not even contacted by our new business banker, we only got their details when contacting our bank to find out why we were unable to transact on our account. We are bitterly disappointed and are looking into other options for our business transactions.
