Customer care just as shocking as their Wi-Fi service

Not only has our Wi-Fi connection at home been absolutely shocking to say the least for the last 2 months, I am STILL waiting to get some sort of response from a ticket that was logged 2 MONTHS AGO. NOT ONLY THAT, when you try and go on the app to cancel their services the app glitches and does not give you the option to cancel. I need this service cancelled ASAP, because I am tired of paying for a service every month that doesn't work!!!!!!
