Network connections

Very poor service, I have been struggling with network connections for the past four weeks. Their call centre consultants always give different version of why my problem have not been resolved. I asked them to send a technician and I have been waiting for one since the 19th, I was told turn around time is 24 hours and when I called the following day I was then told that the problem isy socket I should change the socket. I tried all sockets in the house the problem still persist, I then called and I was told that sending a technician is expensive 😔 but they are trying to resolve the issue. Later in the later I called and I was given a technician's number but was told I would carry the cost, I asked why and why don't they bother giving me feedback, same story the consultant told me he will escalate the matter. Yesterday I called and now I'm told turn around time is 3 to 4 working days, the quest was I am I getting different versions, I was promised that today before 12:00 a technician would be assigned. I called again and I am told that a technician was assigned but not sure when when they will be in contact with me. Can you just pls cancel my contract and reimburse me for December because already it's paid. This month I did not use your service at all since I had no connection at all.
