Who called from 3604601821

Got a call at 11.32, didn't answer. Called back just now and got a busy tone.

ooh... googled this number further - found out from a few other sites like this that the caller called a bunch of people this morning, selling health insurance.

Called answered and they hung up.  Autodialer.  
Did not call back, not a member of Steam.
Sprint cell in Michigan.

They are selling life insurance...

My number was called today.  This number is not in my Steam account.
