UNPROFESSIONAL SERVICE FROM ABSA

I am Businesses owner and received errors when trying to effect payments, After enquiring from ABSA they informed me that I did not provide them with my FICA documentation and my account is therefor frozen. I went through my emails and discovered that they ONCE requested the documentation during Aug 2020.No follow -up request , No telephone call from Business banker. We were then further informed that our Business Banker is not with ABSA anymore and that we have a new Business Banker ,no introductions whatsoever!!!! Our office provided our FICA documentation however since then NO response after several emails and telephone calls. Employees and Creditors can't be paid due to the fact that the account is still frozen.
