Who called from 7204142678

I have received several phone calls in the past several weeks all from the 720 414 2678 supposedly from General Electric wanting me to 'UPGRADE' my home security system. The calling agent NEVER identifies themselves as General Electric or anyone else. They start in by asking personal questions. I do not give out any personal information no matter who the call is from until I KNOW who is calling. They will not answer those questions when asked. When you tell them you are not interested in what they are pushing, they get belligerent and sometimes downright nasty about it

This number keeps calling and hanging up. I have been getting calls from Security One stating that GE owns them and wants me to change alarm carrier from ADT to them.

This call was from some sort of promotions department.

Caller has job offer for an Agco job?  Knows daughter's email address and claims he's sending her info on the job.  Name of caler- Tyler.

Caller ID says "BREAST CANCER S".  Left a 1 second voicemail.
