Supersonic bad customer service

I have 5 contacts made since the 31 of March and still I’m getting the help I need as I need to make payment for my WiFi as my card details changed. I’m chatting to them online but the advisors takes up to 30 min and longer to respond or even help you and this in not the first time it’s happening, the customer is extremely bad and think they should get training again as they have no urgency to assist customer, if you call into the phone line you in a call que of 40 minutes and that is unacceptable as no one has time wait 40 minutes on a call to get assistance.im really not impressed with this service
