Capitec business closed my account

Capitec Bank blocked my business account. I'm a trader and I received money from my client. They have decided to block my account saying is suspected of *****. I have provided the proof of payments that they have asked but they still not helping. I have called several times and they keep telling me my matter is still under investigation. They told me my account will have a way forward within 48 hours but now they keep saying there's nothing they can do to help me. There is nothing as frustrating as calling them and they keep telling you same thing that they can't assist. Why is my account blocked in the first place. How should I pay for my debts since it's month end? I want my account opened. I'm tired of busy wasting money and calling without a way forward. All those agents are not taking my matter seriously.
