Stupid fake security system garbage. I pressed the number to be removed  from the "call list" on a previous call from a different number. I still get the calls but from different numbers. Also got 1 from Georgia today.

Got the call but fortunately didn't pick it up. It's a security system spam. Block them.

I did a search for this numbers location and found the loaction ping showing it in an area of what is called the golden triangle.
South East of the corner of Broadway and Hwy 40 in Denver Colorado.
The only building that interested me near the ping was the Emergency managment office the rest of the buldings were various government buildings. Why? are they doing this?
I received one other call from a Pitsburgh Penn. City area of Atherton. Also government buildings.
The message on the recording mentioned Federal security and having security and I then hung up on them.

It's a scam.

Called my phone today. Left no message.
