I got a call a few minutes ago, no voicemail

Who is the owner of this number? Why are you not answering your phone after I tried calling back to see who this was? Don't call my phone if you're unwilling to leave a message or answer your phone.

Caller ID:  (no area code) 802-9871  Midwest Tech
My own # has a 314 area code.

I answered the call (is it a coincidence that I am searching for a tech job and their caller id name = Midwest Tech?).  Although it quickly became apparent that the call had nothing to do with my job search, I listened for a minute or so.  She wanted to send me a $200 gift/spending card to Walmart, but it would cost $1 for shipping and handling.  I didn't wait to hear more details; just told her I didn't believe it, sounded fishy, and hung up.

I got a call from thin # but I didn't answer...

They did  the same thing to me but they started cursing at me when I would not give them a credit card # for shipping . SCAM
