Unfair treatment at Capitec bank

After capitec froze my account account regardless of me proving that we did everything the client wanted and provided on the qoute through screenshots and written qoute that the client approved , my account still remain frozen, we tried going back to the client to finish the end of the deal by putting the locks and opening water we received a call the client telling us she doesn't want us at her property and she had called the bank and sorted out our accounts to be unfrozen {which was clearly a lie} 2 days later my account is still blocked today we told her again to give us her account so that we can refund her of the work we didn't do according to a quotation she sent us her account than she said she had to also fix the floor so we asked the invoice of the guy who fix the so we can refund it also she went back and deleted the whole conversation including the account number luckily we had already screenshot the conversation clearly the woman is daylight robbing us using my frozen account as bait because she knows i will do anything for my account to be unfrozen. So she gets the money and the house, my account remains frozen and it my loss? Capitec does even bother giving me any feedback or do a thorough investigation visit the woman's house if it must ask her for proof
