DSTV MULTICHOICE CANCELLATION

This now the second review of extremely bad service from DSTV Multichoice when attempting to cancel the DSTV Service. My wife Lorraine cancelled this service toward the middle/end of December 2017. Since then I have been harressed through sms's, emails and telephone calls to pay. For what I don't know? DSTV is paid for a month in advance and the tell me I owe something like R202.25 for apparently 6 days. I asked this person "Dinah" for an explanation and to date, nothing from her! I am a pensioner and cannot afford DSTV any longer for a service that has repeat after repeat of programmes plus there is probably 90% of the channels that are absolutely ******* or channels that we cannot understand. DSTV MULTICHOICE do ABSOLUTELY NOTHING for Pensioners as this service is far too expensive for what they offer! I then got a call from DSTV's Insurance Company asking for the Insurance for the DSTV Explora. What I can for the love of me understand that when the DSTV was cancelled, why the Insurance wasn't cancelled as well? The Lady from DSTV's Insurance kindly sent me confirmation that the Insurance was cancelled. But guess what I subsequently received another sms that DSTV have not received payment from me to dial urgently: *120*68584# for where and how to pay. "Should we not receive payment, we'll request a external collections company to collect!" I am now totally DISGUSTED at the harrasment I'm getting from DSTV MULTICHOICE. Is this how they treat all people & pensioners who cancel their DSTV Service when they don't have a contract with the? TOTALLY DISGUSTING in my opinion!
