Who called from 3038186413

Hang up on answer

Called both my office and my cell phone. Heard a "valid number" comment before the hang up on my office line. I didn't bother answering my cell phone, and they left no message.

Same here, I got a call from this number on my office and then on my cell.  2 rings then they hung up.

Hung up on answer.

Also got a call on my office and cell.. When they called my office I picked up and heard a woman say "wrong number" and hung up.. Im guessing its someone verifying business card contact info
