Blocked account for over two months with no valid reason!!

My account has been blocked , it’s going to two months now of unresolved issues. They said it’s for security reasons. They asked for documents which I provided. My client that sent me the money was also contacted. He verified everything with the bank but yet my account is still on hold. I asked if there’s any red flag on my account? My clients account. They said no! My account is fine, as well as my clients account . None of the accounts was reported or red flagged. I’m not getting help!! And I got bills to pay. My business is stuck. I got services to render to other people but I can’t because of something I don’t even understand why my account is blocked. They keep on sending me to fnb (my clients bank) to tell them to help me. But how can a bank that I’m not banking with help me with my absa blocked account. I was never given a valid reason as to why my account is blocked. If it’s security reasons, they already called my client and fnb bank. Why is my account still blocked? I’m calling every single day, different accountants telling me different stories. I’m fed up of this bank. I just want all my money withdrawn and they can close they’re account , what kind of nonsense is this??
