Over Draft For Cheque Account Settled But Still Active And Charges Are Added

My name is Dikeledi Rosinah Selemela, ***/ABSA My email address is ********** i had an overdraft then i was handed over to LGR Incorporated Recoveries Agent ABSA Bank Division for collection. I made a payment arrangement with Cicelia Maphumulo of which a discount was offered to me, im done paying that account but it is still active and accumulating monthly charges and it still has an outstanding balance of R1999.00 WHICH I DO NOT UNDERSTAND HOW? WHEN I HAVE PAID UP AND RECEIVED A SETTLEMENT LETTER FROM THEMBA NTULI STATING THAT ABSA HAS NO FURTHER CLAIM AGAINST ME IN RESPECT OF THIS SPECIFIC ACCOUNT. I WENT TO ABSA BRANCH IN BROOKLYN THE CONSULTANT WHO ASSISTED ME CALLED THEMBA NTULI AND HE SAID I WILL BE CONTACTED WITHIN 2 WORKING DAYS WHICH HE NEVER DID. I HAVE FORWARDED HIM EMAILS FOLLOWING UP AND STILL HE DID NOT REPLY. I HAVE EMAILED CICELIA MAPHUMULO AND JEANET BESTER, NONE OF THEM REP****. I TRIED TO CALL THEIR LAND LINE NUMBER STILL THEIR PHONES ARE OFF. THE CONSULTANT AT THE BRANCH COULD NOT ASSIST BECAUSE SHE WAS TOLD THAT THESE PEOPLE FROM LGR Incorporated Recoveries Agent ABSA Bank Division HAVE TO SEND AN INSTRUCTION TO THE BANK IN ORDER FOR THIS ACCOUNT TO CLOSED, THEMBA NTULI CLAIMS THAT HE HAS SEND A REQUEST FOR THE ACCOUNT TO BE CLOSED OF WHICH THE VERY SAME ACCOUNT IS STILL OPEN. CAN SOMEONE PLEASE HELP ME. I REGRET THE DAY I WALKED TO ABSA AND OPENED THAT ACCOUNT, ITS THE WORST BANK I HAVE EVER BANK WITH AND I WILL NEVER DO ANYTHING WITH THEM EVER AGAIN.
