Poor service

Since Friday (two days ago) my Dstv was giving me problems. After numerous phone calls, false information etc I finally managed to get a new smart card for my Explorer. False information given, was for instance that a branch is opened until 18:00 on a Saturday, but at 14:20 the branch was closed. Also asking for the address for the Centurion branch, I was given an address in Wonderpark. Finally my explorer (primary decoder) is working again, but now the secondary decoder does not pick up a signal. I phoned customer care again, and the consultant who assisted me, did not take my ID number or account number. She just said there is nothing she can do. Check your cables, that is all. Firstly, if my decoder is built into a cabinet, who will pay for an installer to come out. Secondly, if I have checked the cables (not that I can imagine that the cable could be the cause of the problem, and it is still not working, can anybody tell me what to do, as DSTV can't! The call centre did not even take my name or anything, to verify my credentials!
