Who called from 3852293041

says my phone number was selected for a prize if I just answer these questions.  I'm on do not call list.

they keep calling no one speaks it's a robo dialer

I received the same call. Some woman asking to speak to a manager and when i told her this was a large facility and if can know what she wants I could direct her call better. She then goes on to state, "Well since I have YOU on the phone...." and that is when I hung up on her.  If you don't know who you are calling then DON'T call!!!!! Waste of my time.

caller is unknown calls repeatedly and does not communicate

I've received somewhere between 2,000 and 3,500 illegitimate phone calls at my place of work during the past 5 years or so.  The formula is almost always the same:
1) Call from an unrecognized area code/phone number
2) I don't answer (anymore)
3) No message is left
99% of the time, this indicates an illegitimate phone call.  Those interested in our services leave messages.
