Poor service

I have had dstv premium for many year in mid August 2019 I started having problems where certain channels were blocked from my viewing. Also I noticed my dstv seemed to start up differently from a stored loader version. I reported it to dstv and I have been given nothing but the run around. In October I have paid R1000.00 for the month and I have not had access to dstv from the start of the month. I have visited their offices 3 times. There is nothing wrong with my decoder, there is nothing wrong with my cables or my satellite. I took pictures and sent it to them. Still no dstv. Finally when I reported it again my dstv signal strangely enough got cut. Then I phoned again yesterday and asked for a refund if they can’t provide a service. Only to be told they will send a technician, however no technician has come nor has anyone called me. I want my refund. If you can’t provide the service. Give me my money back.
