UPDATE
There is currently 80 numbers I have logged for US tech support and all their fake software entities, after I recently came across 19 newly discovered area code and toll free numbers they are operating, which are all at the bottom of this post
They have numerous websites listed here
I recently discovered multiple numbers along with this entity they are running
https://sas.guardstreet.com/contacts/new
Along with multiple toll free numbers associated with these old websites
Also a Facebook site they opened for support .com, with the last post on May 10 2023
They have changed the entity of numbers many times, but all numbers are them despite what the menu has changed to
