Terrible customer service from Supersonic, don't sign-up

I called Supersonic on the 1st of Feb with regards to a move, up until today, finally called for the last time today waiting over an hour. I told the agent that I was trying to request for a move but could never get through and I think I just want to cancel, he then asked for my name and ended the call... I have called, WhatsApp messaged and sent requests through but nothing. How can I be paying for a service I am not going to be receiving. I can only cancel on the 31st of March as per the Supersonic app and have already moved... I understand there is a waiting period for Fibre installs but no communication from Supersonic when I signed up I received quick communication what happened?
