BAD SERVICE - WAITING FOR MY REFUND

I WILL LIKE TO EXPRESS MY DISAPPOINTMENT ON MTN SOUTH AFRICA THE BAD SERVICES I RECEIVED BEING SENT FROM ONE AGENT TO THE OTHER IT LOOKS LIKE NO ONE KNOWS WHAT THE OTHER HAND IS DOING.

I WAS TOLD THAT MY ACCOUNT IS BEEN PAID UP BY MTN AGENT ON THE PHONE AND THAT I MUST GO TO THE MTN STORE AND CLOSE THE ACCOUNT BECOUSE IT HAS BEEN LONG PAID UP, WHEN I GOT THERE THEY CHECKED AND TOLD ME THAT THE ACCOUNT IS PAID UP INFACT MTN OWES ME R1700 THAT THEY MUST REFUND THEY GAVE A REF N AND TELEPHONE NUMBER TO CALL. I CALLED AND THE FIRST PERSON I SPOKE TO WAS TSIETSO M WHO ADVISE ME OF SAME AND TOLD ME TO SENT MY BANK STATEMENT FOR THE REFUND OF WHICH I DID WHEN AND SHE ALSO INFORMED ME THAT THE REFUND WILL TAKE 7 TO 14 WORKING DAYS WHEN I CALLED TO CHECK I SPOKE TO YOLOKAZI M WHO ADVISED ME TO SENT THE SAME THINGS BUT KNOW THE REFUND WILL BE 21 WORKING DAYS AND WITH NO FEEDBACK EVERY TIME I AM CALLING RELATING THE SAME PROBLEM TO DIFFERENT PEOPLE WHO DON'T BOTHER TO COME BACK TO ME I'M JUST TOLD TO WAIT FOR 7-21 DAY SO FAR I HAVE SPOKEN TO SO MANY AGENTS VATHISWA M, THULISILE M,PHILISIWE N, TODAY I SPOKE TO 4 WHICH IS FEZEKA, ELAINE AND UYATHANDWA IM BEEN GIVEN DIFFERENT REFERENCE NUMBERS AND TOLD THAT I MUST CALL FOR UPDATES AS THEY WONT BE ABLE TO CALL BECAUSE OF TOO MUCH WORKLOAD. I WAS TOLD TO HOLD THE LINE FOR THE SUPERVISOR WHO NEVER SPOKE TO ME. SO NOW TELL ME WHAT TO DO TO GET MY REFUND.
