Who called from 2137255376

Just received a call from this number on my cell claiming they were from a security company offering a free trial of home security for merely posting the security sign in the yard.  This is a SCAM and not legit..these people actually want to obtain information about your residence and personal information for criminal activity.

Received call on cell phone.  Identified themselves as "Homeland Security Group"

Just got a call from this moron. Wish our Congress would start to work on the issues most people are pissed off about like credit card fraud and unwanted calls. What a terrible waste of time and money.

I started call from this number and when i called back the phone disconnects, even if i call back from a land line.

Not sure why this number is calling me
