Extremely bad service

I am really very disappointed with the service provided by DSTV. I have been struggling with our business account since August 2021, I have sent numerous emails to ask for an explanation on our billing, but no one cared to explain it. We also had a problem with channels not being activated and this problem lasted for months and has not been sorted out yet, we are paying for 13 channels, but only 10 are working. First it was only 8, at least it is 10 now!
