I am getting spoofed calles supposedly from Comcast.com, from legitimate Comcast numbers. Some claiming that they need to talk to me about upgrading my internet home security, some about upgrading my automated home (I don't have any).

BTW I know that they are illigetimate because I am a retired Comcast employee and I know how you work.
