Bank account frozen unnecessary HELP!!!

I am very disappointed in capitec, I have been with capitec for many years and can't believe the service I received, I have a online business and get payments daily , Someone paid R1000 into my account and like any other day I thought it's a payment from a client, so me waiting for client to say listen I paid money in a few days later my account is gone , Phone the bank my account is frozen mhh for why ? I didn't do anything wrong... The complaint: This person said she was paying her daughter from her capitec app to absa bank and then the money went to my acc .. Why didn't capitec phone me to ask for a payment reversal??? I handed in a affidavit, have phoned a few times , everyone says this is really suspicious... nobody phones me back to give me a answer on what is going ons ...This has cost me money and wasted so much of my time...My Debit orders failed and who must pay for that ? ME???How can I be held responsible for something that is not my fault this I ridiculous... Almost struggling a month now ...
