IMPOSSIBLE to cancel MTN home internet month-to-month contract

Home Internet Cancellation- Month-to-month contracts: I have been trying for more than 2 weeks to cancel a MTN Home Internet contract that was originally taken out through the rewards team. I have done all the steps required by MTN to cancel the contract. When trying to follow up, know one at any of the call centers can give me an answer if its been canceled. Have been to the MTN Ceres Branch twice but to no avail. Have spent endless time wasting on phonecalls where the operators just shrug their shoulders and say I must go back to the branch to cancel! But I have done that twice already. Today I got an MTN message to say :"We see that you are not longer canceling the Home Internet any longer. Good choice!" I mean WHAT????!!!! And I have just spent another useless 2 hours kn the phone phoning MTN customer care and the Rewards team, with just another "we can't help you". Pathetic MTN....I want my debit orders money back that you CHARGE IN ADVANCE but I don't have MTN internet since 27 Nov when I returned the router to Ceres Branch. Extremely bad service all around
