Who called from 7204457315

I got this call and did not buy a security system.........

Just got one too that said Denver, CO.  I never answer calls with no specific ID

Another one of those calls with caller ID [insert city]     [insert state]. Notice the big gap between city and state, that can't be suspicious at all.

Same nonsense to my DNC home phone. The DNC Registry is at best a joke, at worst a numbers list for scammers to abuse

Pure fantasy. The DNC list operates exactly as it was intended. For honest business' not to call you. If you are getting telemarketing calls, and are on the DNC list, you are being called by foreign, or domestic criminals. The intent is to steal personal or financial information from you. Criminals will not obey the DNC or any law. Why would they? Laws are in place, but the individual must take personal responsibility for their protection. Just as you lock car & house doors, you have to treat your phone the same way. Look into using technology to block or limit such calls.
