The worst bad customer service!!!

Went to the agent in Menlyn after being reffered by dstv to them to clear an error message on the decoder but I was told to swapp my decoder to the explora 3 but it did not connect and also they failed to link my smart card to the new smart card, then due to the bad service I then requested a refund after returning their not connecting explora 3, the worst thing is that their refund takes 7 to 15 days to be processed. If they can’t give the best service they can’t
