Who called from 8574884844

Received a call from this number. A guy spoke my first name right, but obviously not know me. Just told him that he dailed the wrong number

received call....no vm

Calls my number evert week.

Called again today. I'm working in IT.

I also work in IT and received a call from this number today. I think they may just be trying to verify names<->numbers and then building a list of leads to sell as "verified" (more valuable).

The reason I believe this is because they hung up on me immediately after confirming my full name.
