This number called my cell. No message left.

Has called 3 times around 3 or 4 pm and left no message.

Called again today, went to voice mail, no message just road noise. A Stalker??

I got a call from this number three days in a row now.  Finally today someone said something.  She offered to have me participate in an automated survey for a $50 gift card to spend at Target or Wal-mart.  A chance to win one.
Anyhow, it goes into the recorded stuff and you press 1 or 2 depending on your answer.  When it got to student loans, I pressed one and a guy came on saying welcome to today's sweepstakes.  I asked him to remove me from the list.  I smell a scam.

You smelled correctly
