DSTV are *******!!!

I have had multiple problems with my DSTV account but recently I have received terrible service and with numerous visits to the agencies and call to the call center but no assistance has been provided. After the first visit I was provided a new decoder as I have insurance, I get home and it’s faulty. Than I go again and again they provide me with a new decoder but they don’t pair the device. The staff is *********** as they definitely shouldn’t release the decoder if it’s not working. I’m sick of DSTV and want a refund because it’s been over two weeks that I have no DSTV plus I had to pay a technician 3 times to come out only for them to tell me that I have been given defect decoders.
