Who called from 5039028131

Just received a call, no message, and I do not answer to unrecognizable numbers.  Very irritating with all these telemarketers.

Called me twice, I picked up both times and they didn't say anything.  I sat on the phone the second time to listen and they hung up first.

That number called me too.

just got a phone call from this number. did not answer it and they left  no message. im in georgia.

Same thing...called my cell phone and left no message - I am in Colorado
