I don't consider hounding people with robo calls trying to beat them into submission as legit.
You people are worthless maggots,  harassing people,   and I wouldn't buy anything that you're selling including your post.   I'd like to get a grip.   Right around some unwanted callers throats.   Consider that a threat,  [***].

as a former marine, you r such a liar, 6ft 8in in the rangers    OK

These bozos called on my Android cell #, but these scamming creeps don't care if they break the law.  It's SOP for them.. needless to say.. Android's make it easy to black list a number.. just pull up your call log.. place finger on offending log entry.. keep it their until menu appears, select blacklist.. done..

SCAM SCAM.

This company is offering a "free" home security system. I did some research and found the following info:

COMCAST PHONE OF MICHIGAN, LLC
Comcast Phone of Michigan, LLC operates as a subsidiary of Comcast Corporation.
29777 Telegraph Road
Suite 4400B
Southfield, MI 48038
d/b/a Comcast Digital Phone ( Comcast Phone)

D/B/A CIMCO, A DIVISION OF COMCAST BUSINESS SERVICES
347-775-2743  (alternate phone number??)

I could not find a phone number for them other than the one they called from and the alternate number shown above. Their corporate profile does not show any officers.
