Remove hold on my account

Remove hold on my account, Capitec blocked my account saying I receive *****ulently money and I did went to the branch confirming that I didn't do any *****, and they said I must do affidavit and bring my certified ID copy and they will remove hold on my account, it been 2 weeks now and hold is still there and what confesses me is why did they put my account on hold since they remove that money that they suspect that is *****ulently and now my life has stopped because of them, so remove that hold as soon as possible. I need my money on that account
