Unfair handover

So ABSA could not help me with unauthorised debit orders to a point where it hindered my ability to fulfil my legitimate debit orders. I had a positive balance on the account when I had no option but to get my salary paid into another bank in order to avoid not being able to fulfil my other financial obligations. They then sent me an sms last year from Tsebane saying I have been handed over!? I then sent an email to *** advising the situation. Never heard back from them, now I have an adverse listing on my credit profile, affecting my ability to find employment during this hard time. Firstly, I have not received any statement from ABSA indicating the outstanding amount? Statements were usually sent by email. As a service provider they never tried to make payment arrangements or advise any outstanding amount before being handed over? It is really the poor that suffer at the hands of these Banks. They were unable to protect my account or even give me details on who was debiting my account and now I have to be the one that pays?
