ABSA REVERSING DEBIT ORDERS WITHOUT MY CONSENT !

ABSA HAS BEEN REVERSING MY DEBIT ORDERS WITHOUT MY PERMISSION FOR 3 MONTHS STRAIGHT NOW. I HAVE GONE TO SEVERAL BRANCHES WITH MY BANK STATEMENT TRYING TO DISPUTE THIS BUT ALL THE EMPLOYEES ARE USLESS AND INCOMEPETENT BECAUSE NO ONE IS UNABLE TO EXPLAIN WHY THE DEBIT ORDERS ARE REVERSED ,ESPECIALLY BECAUSE THERE ARE ALWAYS FUNDS IN THE ACCOUNT. NOW MY ACCOUNT WITH TELKOM IS IN ARREARS BECAUSE ABSA HAS BEEN REVERSING MY DEBIT ORDERS . WHAT THE HELL IS GOING ON AT ABSA ?????YOU ARE A VERY TERRIBLE SERVICE PROVIDER BECAUSE EVEN YOUR OWN EMPLOYEES CANNOT EXPLAIN WHY YOU KEEP REVERSING THE DEBIT ORDERS.CAN YOU PLEASE ADVISE AND FIX THIS ???MY CREDIT SCORE IS BEING AFFECTED BECAUSE OF YOUR INCOMPETENCE AS A FINANCIAL INSTITUTION.
