Who called from 4842604012

Call on my pre paid cell that no one has number to and says nothing.

Called twice in one day - did not pick up because I saw these messages. I get scammers calling all the time.

I work at a law firm and they keep calling my direct line.  The caller ID just shows "SURVEY."  I ignored the calls then called the number back just to see what would happen.  Got a repeating recording saying "Hello and thank you for calling.  If you'd like to be placed on a do not call list for the number that called you, please press 1 now."  Definitely didn't press 1 because then they would know they have a "live" phone line and they'll continue the harassment. They eventually stop if you never answer, but unfortunately, sometimes it takes a while.

and if you return call, you cannot get a person

Robot scam spam call. Blocking doesn't do any good. They just call back using a different # the next day.
