DSTV has no value or customer service

I have requested cancellations multiple times, because the streaming package is **********, and is always buffering or losing signal, but I still get charged, but my service was cut on the day I called. Then I get a sms stating that my account will be debited on such and such a day for a service I no longer even receive. Not only that, they have combined my details with my sisters, so they are stating I don't have an account but all my details are on the system but under my in laws name... they have no idea what they are doing, and while I'm on here, their programming has gone to the birds, absolute ******* and repeated content from.years ago, definitely no value for money.
