The worst service I have ever experienced. Ever

On the 2nd of December, The MTN network went down and effected Supersonic's Fixed LTE plans. Supersonic themselves were aware of the issues as it was an automated response on when you called their customer support. I called everyday to try resolve the issue. Only until the 17th of December, I was able to create a case for a faulty tower and was told that my speed was so slow because my router was trying to connect to the next closest tower, but it was very far away. My internet speeds was only 2mbs but I had to work, as I do from home.. I called on the 24th of December to try my account credited for the very slow speeds and issues I experienced. I got a call from a lady named Francois who told me she was the Line manager. She informed me that due to the nature of my case, me being on the new uncapped LTE package, that they do not have a procedure yet and that she will escalate it even further and provided me with a case number. She also promised to call me at the end of the month. I called on the 3rd of January to follow up as I never received a call back. The agent told me that my case is resolved and that I will get a credit for February's billing. I have just received my invoice for February and no credit is on it. I called today and the agent told me that the case was for a credit over November but I only joined on the 23rd of November!! She also said that they saw I had usage over December and that I won't be credited. How is it my fault the tower went down? Why is it my fault that I had to use the internet as best I could as I need to work? So in Supersonics mind, if you report slow speeds, you need to disconnect your router completely and not use it all.. I mean how pathetic is that? I want this sorted ASAP. Absolutely ridiculous.
