InferiorSonic - Zero Service

A rating of 1 star is overstating how bad Supersonic are. 0 Stars. I am trying to contact them about an outage I have with my fibre. Absolutely NO response from call centre. I have been holding for 30 minutes now. Shocking! The WhatApp service is also down.... How do you actually service people, if none of your service channels work????? Can't even register on the client zone. How do I cancel my subscription?
