Account and funds on hold

Capitec placed a hold on my account. Placed my funds on hold. When in enquired I was instructed to get an affidavit, provide proof of payment and ID. Which I sent through to capitec ***** department. I was instructed that my account won't be opened. But my funds need to be returned to me. Capitec can't with hold my funds. This needs to reviewed further. These are my savings funds. I also need official written communication from Capitec and a case number.
