very dissatisfied with supersonic network and customer service

After numerous calls to complaining that I am not receiving any signal. the call Centre agents would troubleshoot with me my signal would be restored but not even last for more than 2 hours. then I would use my own data until again I would take the time to sit on the phone and again the same thing would happen. eventually could not take this and cancelled my services with supersonic. now they were very responsive and billed me the claw back fee. I disputed this as I am cancelling due to them not offering the services that I pay for they are the ones who are not holding their end of the contract and not me. I have lost a lot of time being unproductive at work because of Supersonic non working internet, I have spent a lot of money using mobile data while paying a full subscription. calling the call Centre to get resolution makes things worse. no one knows their complaints procedure, or escalation process and there is no way to get hold of their escalation department all the call Centre agent could do is be irritated at me and tell me someone will contact me and that she wanted to pass me to someone else to talk which is also in the call Centre that would not be able to resolve my issue. the amount of time spent as a customer trying to just get what I paid for and now the amount of time spent trying to move on to another service provider is appalling.
