Unsatisfactory service

Have been having problems with our WiFi since the 25 January 2025. Eventually got to speak to somebody on 11 February 2025 and was told that some settings on the router was incorrect and it was corrected. It only lasted 4 days and we are back to square one, it is buffering all the time and you can’t get a technician at the call centre to talk to and get assistance. Have been trying for 2 and a half hours this evening and eventually got a person by the name of Aoyla Mamela and had to do a speed test send it to him and to be told to watch the progress and report back to them. When I said that they need to sort it out he told me that I will have to pay for a technician to come and sort it out. Reference number that was emailed to me is #2647619.
