Supersonic Bad Service

I had wanted to switch my fibre supplier on Supersonic but their customer seevice is pathetic, everytime you try and get hold of any department that is not sales it takes 15 to 20 minutes on hold. I called to cancel my subscription on 1 April and was told its a calendar month however I can only do it from May which in essence is actually 2 months calendar notice, this is absolutely ridiculous. I had also just wanted to switch suppliers but stay with Supersonic they aren't able to help until June and then I need to call back once again to start the new service. We never have any signal, the 5G doesn't work at all and yet the price increases all the time and yet we are forced to be locked in and endure the ridiculously long hold time trying to speak to a consultant
