Continiuos disgusting service

I logged my 1st HP complaint over a week ago & that was the only way someone contacted me, however my issue is still ongoing with their disgusting service & lies. I received no email correspondence as advised by the previous consultant. Installation only happened on 16 Dec after I had to run after the installation company. I am in the South of JHB yet the installation company assigned was in Honeydew. It took 4 days and me calling around like an idiot to beg for assistance. Therefater all the installtion guy did was plug my decoder in as there was an existing dish, so no installation done, I could have done that myself! I took out price lock and told 1st payment will go off in Jan 2021, now i get an sms saying it will go off in Dec and the amount is higher than the price lock amount i agreed to! I was also told that I can view the program on a 2nd TV from the primary decoder, now the installation guys tell me NO i cannot get it on a 2nd TV! I am fed up with the **** service and lies that is being told! Should I cancel or what should be done because DSTV is processing sales based on false pretenses. I called again last week and was told that someone from the journal dept yet no one has called me. I've spoken to so many people from this org yet no one bothers to call me back or resolve my issue!
