Who called from 9292294593

Answered and said hello several times. No one said anything and then the phone disconnected

I have 2 missed calls. No voicemail was left. Just want to know who it is and how to not have them call.

They just called me and I tried calling back and t says the number is no longer in service?

Strange if this number is no longer in service must be a scam.  I just got a call from this number and there was no message left.   Grrrrrrrf

I got the same "no longer in service message," and I called back 30 seconds after they tried to call me.
I get a LOT of Student Loan Refund calls, so I'm guessing that's what it is, but I don't know for sure since this caller never actually says anything.
