Capitec closed my account

Capitec Bank blocked my account for no good reason. I received R2.6k from my client as she was paying me for selling a weave to her. Capitec then decided to block my account saying its been suspected of *****. I have been calling them back and forth ready to provide any documents they need but they are not helping me. They first told me that my account would have a way forward after 48 hrs and after that set time frame they told me that there's nothing they can do to help me. One of their consultants even put me through to the ***** department and they told me that they are not the relevant department to deal with my case. I am so frustrated because debit orders are supposed to go through on the 15th but I don't what will happen as my account is blocked. I don't even want to talk about the frustration of not being able to transact online and withdraw money yet you have it in your account.
