Worse service ever!!!!!!!!!!!!!!!!!!!!!!

Mid April we called them to cancel our DSTV as my husband lost his sighed and he was the one using it. So may they still deducted there fee of R659 I phoned them again and 6 days later again .We are now in October and they are still deducting money although service was cancelled in April. I send mail upon mail but now one cares to even reply.
