Who called from 7047769898

This phone number dialed my phone.  I did not recognize, and did not pick up.  I googled the number, looked suspicious.  Said it was a land line in Monroe, NC.   I called the number, and a message said
No longer in service, or has been changed.

There is a growing concern that many of these suspicious numbers are bogus, but could be used
to steal your phone/internet,  data, identification.

Got a call from this "unknown" number too.  Didn't answer, as all my contacts have caller ID displayed.

Robot called my cell phone trying to sell insurance.

I got a call from this number just now and I missed it but I called back and it said it wasn't a working number.

I just received a call from this number. My cell number begins with "776"-this is harassment! It was a recorded call. When I tried to dial it back from my land line, the message states, "We're sorry, your call cannot be completed as dialed." I am on prepaid cell now because I went back to school. This number needs to be stopped; where/who can we report this to that would do any good?
