CUSTOMER SERVICES SUCKS BIG TIME

I HAD A LOAN WITH CAPFIN IN MARCH I SPOKE TO A CONSULTANT TELLING HER TO DEBIT HALF OF THE OUTSTANDING AMOUNT AND THE FULL AMOUNT FOR MARCH AND APRIL SHE HAD TO PUT THAT ARRANGEMENT FOR ME IN PLACE. HOWEVER SHE NEVER SAID ANYTHING ABOUT EXTRA CHARGE SHE JUST SAID SO END OF APRIL WILL BE MY LAST PAYMENT. SO I HAVE STICK TO MY ARRANGEMENT AND PAID OFF THE LOAN LAST MONTH IN FULL. ON FRIDAY I RECEIVED A CALL FROM A CONSULTANT TELLING ME THAT I STILL OWE THEM R234 ????????? REALLY WHY NOW THAT I HAVE PAID YOU NOW YOU CAN CALL ME AND TELL ME ABOUT THE EXTRA R200. I ASKED THE LADY FOR A STATEMENT AND TILL TODAY IM STILL WAITING. NOW CAPFIN KEEPS ON CALLING ME 5 TIMES A DAY. ITS NOT EVEN 7 IN THE MORNING YET AND RECEIVING THREATENING MESSAGES .WHY DID NO ONE TELL ME BEFORE ABOUT THIS R234, WHY NOW THAT I HAVE PAID YOU YOUR MONEY CALL ME 5 TIMES. AND I DONT WANT YOU TO DEBIT MY ACCOUNT NOT AT ALL
