ABSA ************s

For almost 9 weeks I have been trying to get an explanation from ABSA as to how my account could possibly go into overdraft without ever having a facility. How it it that debits were not rejected for lack of funds. I had one call from Mr Machema, another from Mathephelo Somo attempting to explain to me how this happened. My requests to inform me in writing have not been honoured despite their promises, meanwhile I am charged interest fees every month. This smacks of ******ion - their deliberate refusal to answer my questions in order to ****** exorbitant interest fees from me. I need the explanation in writing in order to take this matter up with the banking ombudsman and the CPA. I previously queried other journal debits against my account by personally visiting the branch for an explanation. I was told that Boksburg would request the details from JHB and I would have my answers within 2 days. Weeks later I am still guessing what the journals debits are for. Yet I was charged interest the end of September and again end of October. How is this allowed to continue? I am totally ignored and threatened to be blacklisted if I do not pay!
