Who called from 3477043831

They just called, and I just blocked!

This is a scam,  was called from 3 different blocked NY numbers in 2 days.  Now security system, previously it was a new gas meter, solar panels etc.  Block all of these calls trying to steal personal information including credit cards.  Can't be too smart to keep calling people who will not respond.

Called my cell phone, did not answer as was an no name #. other people say it's a scam.

Same as several responses including Dixie: Robocall: "You have been referred by a friend for a free wireless home security system."
Does anyone know what can be done about these [***] calls?

They just called my cell left no message. Scam
