Who called from 4165889262

Why r u calling me?

I also received call from this number 1 hour before.

When I tried to call back, it says number not in service

When I called this number back I got a message saying it is out of service.

Hung up when I said hello

Received a call. Phoned back but number not assigned. How do we contact this company to tell them to stop. My next step will be the police if I continue getting calls.
