Who called from 7703704248

Call came through as "Out of area." I let it go to voicemail. No message. Called back within 2 minutes. I picked up the phone... dead air. Blocked! Robo-call.

Ditto, dead air, hang up in my ear

Answered and they said it was 411 and asked me about a business I used to own.  When I told her that I didn't own that business anymore she hung up.
