Channels stopped working again and not getting help

on the 30th of April 2021 some of the channels 112,124,302 just stopped working, i phoned your acredited installers and they checked and didnt find any issue.they advised I take my decoder to dstv outlet to get it tested,and my decoder is works fine on the outlet and took it to my neighbour and it works fine so they came back and repositin the dish,change lnb cables and test with their dish but the issue persisted we phoned your useless call centre they send the command,restore factory settings all the troubleshoot you can think of but to no avail.I phoned again on Friday and Jadene logged a call ref 542790 and advised that the technical dept will call me within an hour and to date i never recieved a call.so today i phoned again using my money for the service am not getting and wow your agents just hung up on me unfortunately I didnt get the name of the first guy,but phoned again and nobuhle hung up on me.then gugu who kept telling me what she thinks and not stating facts and said there is nothing she can do from her side just imagine and say when her supervisor Evelyn come to work shell give me a call just imagine she doesnt even know when will that be so multichoice instead of enjoying my monthly debit and giving me a **** service I need this to be sorted out ASAP and must be reimbursed for such horrible service its no wonder people are cancelling their subscriptions your service is very poor and the same problem happened 4 years back and your technical team has to come and solve this so am waiting for your agent response whoever is going to call me must have solution to this gaaaaa
