Over charge, their WiFi shuts itself off and goes out whenever it feels like and all they do is replace your modem with another refurbished one that still does the same thing. We bought our own brand new and it still happens. They told us we d need to upgrade, so we re paying $96 for WIFI ONLY! Supposed to be able to support 10 devices. We have 5 running durning the day. 3 laptops for the kids for school and 2 smart TVs that auto connect. It is still happening!!! It can t even support the ones I have. This is the worst company and we re forced to use them because all the phone and cable companies divided locations and only service certain areas. Worst company!!!
