DSTV/Multichoice

We have been customers for more than 20 years and up to 4 January 2021 we had no problems. However, on the 4th we upgraded to a XPlorer Ultra and ever since we can not view any programmes. The installer was booked through Multichoice as we answered a sms on 17 December 2020 about a special on upgrades. The agent we spoke to assured us she will arrange everything from her side. she said we coukd install 2 viewpoints. On 4 January the installer arrived. He installed the main and 2nd point and as we wanted a 3rd point he opted to fetch a "modulator" box for which we gave him R800-00. He left to fetch it and came back to install it. He even helped us to install Showmax after I spoke to an agent at 13:25. Unfortunately he deleted our premium subscription and an agent reinstalled it at 15:54. At 17:47 we switched the TV back on and an error message appeared. Once again we contacted Multichoice and were told to get hold of the installer. The agent who answered the call was very rude and did not understand that I had not booked the installer and do not have any contact details. At 18:27 I again placed a call and was told that although my debit order of R1208-00 went through, there was an additional amount of R270-00 outstanding which I promptly paid by credit card. This is also something I have to querie because the special was for R994-00 and not R1478-00. The agent who then answered the call was very helpful. He said he will get the installer to come back but in the meantime he wil activate the secondary line so we could at least watch TV. At 15:34 on 5 January we contacted Multichoice again because the installer still haven't contacted us and an agent named Rofhiwa answered the call. The main and secondary line was off once again nit showing any error messages. She did not even allow me to explain the problem and when I told her she was the 5th person I spoke to she accused me of lying. I asked her for her for the supervisor's number but was told she was on keave but I could contact a person named Irene. She then told me I could not have Irene's contact details as she was not a suoervisorbut that Irene would contact me. However, until now 6 January 2021 at 10:00 she still haven't contacted me. At 16:18 on 5 January I again called Multichoice and Boitumelo Masipi responded. She went out of her way to help us and listened patiently as I explained to her what was happening. She then assured me that she would contact installations and get the installer to contact us. She even called me back to tell me what she had done. At 16:32 we received a sms with a verification number informing us that the installer would be arriving soon. It is now 10:20 on January 6 and still nothing. My debitborder was collected but I can not view anything. What now?
