NO SERVICE RAIN 5G

I upgraded to the new package where you get x2 premium routers for the price of x1. I used the one router at my parents house and the second on at my house. Since day my router has been giving me problems where it switches off by itself and has no internet connection for weeks. This has been an ongoing thing for 2months. I loggend multiple tickets and NO ONE CALLS ME BACK, when I call in I get told to reset the router.... Wich I did x10000 times. I have requested to cancel in December with no luck has anyone called me... I have stoped paying them as I am not going to pay for something that has not been working since day 1. WORST CLIENT SERVICE EVER!!!!!!!!!!!
