I will not pay for service I could not use!!!

To start of I have no problem with VOX except this time, I have been with over a year on ADSL. Now I upgraded to fibre. However ever since I have upgraded to the 100 up and 100 down fibre plan from the 04/03/2022 I have not have any internet connection and I was patient enough for a whole month reporting to them my Wi-Fi is not working. They kept on telling me everything is right on their side but I tell them I am home the I don't have any internet connection and when I do it is only for few minutes but never more than 20 minutes. So I told my agent to request fora technician to come to my house and check because checking it remotely is not working because they see it working good from their side but I still do not have an internet connection. On the 07/04/2022 a technician from Frogfoot came to check the fibre, if not the problem is on fibre itself and it had none. So the technician was willing to help me to prove where the fault might be because he suspected the router. Yes he used the old D-Link router I have and configured it to the fibre line and it has been working since then the 07/04/2022. So I am saying to VOX I will not pay for the month of March because I did not use the wifi for that whole month since installation from the 04/03/2022 and now they have suspended my account. Of which it is fine the lesson from this ordeal is that they should be fair and listen to customer because some of us are clued up and understand how things work, they must stop being big headed. In closing VOX has lost a client because of stubbornness and knowing better than everyone.
