Who called from 8472014257

Have no idea who they are - they left no message

Have called multiple times in the last couple of days.  Leave no message.  When I tried to call back, the call went straight to a nondescript mailbox.

Same thing, I get a bunch of calls each week for the last 2 weeks, call back nada?  LEAVE A MESSAGE!!

I received a call from the lady today.  She said she was calling from "Simply (something - hard to understand)".  She indicated I had entered my name into a drawing and was one of the finalists.  I was in a meeting so I told her to call back later.  She did, but left no message the second time.
