Frozen money

I am a Capitec bank user on the 6th of March Capitec froze R1300 on my account because someone was claiming that I ****med them while I was the person being ****med. I am a seller so people send me money then I courier goods for them. But after the customer received their goods they went to the bank and try to get the money back. How can Capitec take one side of the story and freeze my money that is not fair at all. Please I need Capitec to realese my money. I don't know how I can get help. And there is another story of a frozen R300 they said that I once tried to withdraw money from an ATM and the machine went off. So for that reason why would they freeze that money. I can't remember that but if I didn't get the money surely I was gonna enquire at bank. If I managed to get the money it means it was debit so why on earth would they freeze my money. Capitec is just frustrating me with their poor customer service. After I went to the bank for all this asked the consultant what can I do to get this money back and they said they didn't know maybe I should call the person, like really?.
