Account blocked

Account being blocked.someone transferred money from his FNB account in exchange of cash to my account.Fnb then reported that the person received that money from deposit ****.I called Capitec ***** line to ask why my account was blocked they told me about the 1000 that have been transferred.They told me to write an affidavit which I did and submitted.When making a follow up I was told the case is closed but my account is still blocked.Ive been with Capitec for more than 20years and my salary is a lso being paid in Capitec.What about my debit orders.Even 1 of your consultant by the name nthabeleng from ***** line who was so rude told me to go and open a bank account somewhere since it is unlikely for Capitec to take me back.My salary is being paid in Capitec.I still say I'm in no way involved in that case and can you kindly review this case and give me a feedback.Regards
