Vuma/supersonic service terrible

On 5 March 2021 Vumatel came to install our fibre to home. FIRSTLY, the installation was done poorly with cables bent ( fibre cable) and not neat at all. SECONDLY, we are still not " live" as the tech just left without making sure all lights are green on the modem. THIRDLY, vuma insists that SUPERSONIC is our ISP BUT Supersonic has no record of us. So we have a fibre line, a modem, cant get an ISP as our line is on hold with Supersonic (but they cant find us), and no one is willing to help. Terrible!!!!!!!
