Terrible Internet Service

I am getting terrible internet from past 2 months.

You are citing the replacement of Router device and recommending to use Xfinity Gateway apart from least recommended routers from

other vendors.

My device was never listed in your approved device list from past 2 years and all of a sudden you want me to get a new device or rent for $15/month.

This is robbery, i make sure to slowly close my services with xfinity.
