This website has multiple numbers for different streaming internet TV and phone providers they claim to be via the dropdown header menus.
Most are not currently active but are related to the number for this thread by address references throughout, which have all previously been active and they may activate at any time again.
One page has so many errors it lists 3 separate toll free numbers for the same fake provider…truly pitiful
There are dozens of websites telco scammers have, many reference the same numbers, with different addresses
This number and websites have been active since mid July that I know of
8889646571 AT&T/Spectrum/Comcast X-finity/Verizon streaming TV. internet, phone (no menu) (ViciDial)
