CONTRACT CANCELLATION

THIS IS A FOLLOW ON OF MY DISGUST AT TELKOM FOR NOT RESPONDING TO MY EMAILS THAT I HAVE SENT THEM IN THE PAST TWO MONTHS. I HAVE SENT THROUGH A CANCELLATION FORM ON THE 15TH DECEMBER 2015 AND I STILL HAVE THE CONTRACT AFTER 27 MONTHS OF EXPIRING. RUKSANA FROM THE HELP DESK DEPT SAID THAT SHE WOULD LOOK INTO THIS MATTER BUT NEVER DID - REF NO: SM189276. WHAT THE HELL IS GOING ON? IM PAYING FOR A CONTRACT THAT CAME TO AN END IN NOVEMBER OF LAST YEAR AND SIGNED A CANCELLATION FORM WHY AM I STILL GETTING BILLED??? WHY CAN NO ONE AT THE CALL CENTER 081 180 NOT HELP ME AND THEY SAY THEY DONT HAVE A NUMBER FOR THE CANCELLATION DEPT. I DONT WANT TO HAVE THIS CONTRACT AND I AM GOING TO MY BANK TO CANCEL THE DEBIT ORDER THIS SAT. THEY ARE NOT DOING THEIR JOB??
