Metro Fibre unreliable Wi Fi

Good evening, Metro Fibre did install a fibre WI Fi at my premises. The router was connected with only two wires, I had to connect the internet cable to the TV, all wiring was already in place from the previous WI Fi connection. I experienced problems immediately after installation.The internet disconnected time and again. I reported it several times and was assured that the system is in order now, but it was not, the second day after the installation, the same problem occurs, Metro Fibre technician was supposed to contact me to follow up, but that did not happened, I just got several emails that the system is running now, but the problem still exists, the Wi Fi name did also disappear from my mobile phones and laptop. I told Metro Fibre that if the problem is not sorted after the second day which was Friday the 22nd of May 2026, I will cancel the deal. Friday the 22nd 2026, the second day, I unplugged the rooter and box it and told Metro Fibre to collect the rooter. I send their cancelation department a cancelation notice and told them I am not prepare to pay any cost because I had no benefit out of their system. I had to pay R60 worth of data to compensate for the times that the internet disconnect, I just got a bill of R694.81 from them for two days of unreliable service.
