DStv Supreme Signal Kempton Park

I phoned DSTV to query a problem with an error message E48.32. They could not assist telephonically and requested that I call an “accredited installer” to assist. in November 2019 I called Supreme signal installers, they came out and installed a new LNB which they said was the problem. To date the error hasn’t been resolved. My last contact with them was today where I told the lm that the issue persists and he wants to charge another R350 to come out and resolve the issue which was to be resolved last month. After I told him that I would complain to DSTV, his response was, you’re welcome, as though he knows that there are no repercussions to the bad service.
