telkom refuses to cancel a service i dont use.

I WENT INTO THE FOURWAYS CROSSING TELKOM STORE TO CANCEL MY CONTRACT. I FILLED A FORM AND SENT IT THROUGH ONLY TO STILL BE CHARGED A MONTH LATER. WENT BACK INTO THE STORE AND THEY SAID ITS NOT CANCELLED BECAUSE WE NEED TO SIT BY OUR PHONES THE WHOLE DAY FOR TELKOM TO CALL ME BACK TO CONFIRM IT. I DONT HAVE TIME AT WORK TO SIT AROUND EVERY DAY LOOKING AT MY PHONE. IT IS THREE MONTHS LATER AND I AM STILL BEING CHARGED FOR A SERVICE I DONT USE. TELKOM HAS TERRIBLE SERVICE AND ONCE YOU HAVE A CONTRACT WITH THEM THEY DONT ALLOW YOU TO CANCEL IT AND THEY CHARGE YOU FOR SOMETHING YOU DONT USE. I WOULD LIKE THAT SERVICE CUT AND NOT BE CHARGED FOR IT. AND I CALLED THE CALL CENTRE TODAY THE MAN SAID IT IS CANCELLED WHEN IT ISNT!!!!
