Account blocked for a year with no assistance

My capitec account was blocked last year around the 15th of December with no warning or explanation. A client complained about not getting scrubs that they had ordered while they were on their way to them. Next thing my account is blocked on the exact day that it was falsely reported as well as an account from another bank that I had sent money to. When I attempted to get my account unblocked by providing all the necessary documents my account was still not unblocked. It's been a year now of no assistance from them at all. I got so tired of contacting them and at this point I would just like my account back. They can still send me emails about promotions at the bank from an account that I haven't been using but they can't unblock my account.
