Capitec - *********** bank ever

I am a Capitec client for years, I have a small business which my clients use to deposit the money. so now I had a client that wanted to rent my place and she paid a deposit into my bank account. she was supposed to move in on the 1stof june and she didn't she said she will move in on the 15th on the 8th she sent a text saying she got a job offer somewhere she won't be moving in anymore and that she wants her money back. I told her I can't give her the money back because the place was reserved for her for the month. she then went to Capitec notifying them that she paid the money into my account wrongfully and that she was ****med by me. so now Capitec has closed my account without my side of the storey. I had to go to the police station to do an affidavit giving the side of myh storey still I get no response from Capitec. Again I don't understant why is Capitec intefeering with my account as this is a civil matter and has nothing to do with them. the least they could have done was to investigate all transactions in my account to see if any of them could be labelled as a **** or ***** but they haven't done that. this is the worst bank one could wish to bank with
