Frustrated with Supersonic

I phoned Supersonic two weeks before I moved to inform them that I am moving and I want to move my wifi, a week after I moved they still haven't moved the wifi, I phoned again just to find out that my call wasn't logged, I logged a new call. After a few phone calls where you hold for hours they've send a technician to the new house, I thought okay everything is sorted but no I waited again with no wifi. I phoned again holding for hours or they say I will phone you back with no one phoning, they've send a technician again, the technician tells me that there is a misunderstanding they need to install a new cable, I am still waiting for the cable to be installed after battling now for almost two months no success or update and after phoning multiple times just to hold for hours or being transferred and then get cut off. But don't make a mistake they still take your debit order every month even without supplying you with a service.
