MY ACCOUNT IS A CLOSED ACCOUNT AND I WAS OWING 200, I WENT JET TO PAY THAT 200 NOMSOMBULUKO SAD I HAVE TO PAY 300 AND I DID EXPLAIN TO HER THAT I OWE 200 NOT 300, THEN I GAVE HER 300 AFTER PROCESSING THE PAYMENT, SHE SAD SORRY YOU WERE OWING 200, GO TO EDGARS THEY WILL ASK YOU TO PURCHASE ANYTHING FOR 100, I AGREE, AND I WENT TO EDGARS MAPONYA MALL, THEY SAD THEY CAN DO ANYTHING BECAUSE ITS A CLOSED ACCOUNT. I ASKED IF THEY CAN GIVE A 100 VOUCHER, THEY SAD NO,NOMSOMBULUKO WAS SAPOUSE TO REVERSE THE MONEY THE VERY SAME DAY WHEN I WAS MAKING THE PAYMENT, SO THEY DIDN'T REFAND ME OF MY 100.
