Who called from 7733123229

I have received several calls from this number. If I answer, there isn't anyone on the other end. If I miss the call, there is never a message.  Has anyone else received a call from this number? Thanks.

I have - plus similar 773 312-5119. I don't answer and they never leave a message. Blocking both.

The exact same scenario. No one speaks or leaves messages.

I just received a called from this number and the guy told me he is with College Support Service. He asked for my name and to spell it out. He stated that I applied for a job with them but I did not and when I stated so he terminated the call.

Scam:. Calls everyday.  Doesn't say anything.  When I call back, the number is always busy.
