Missed a call from this number.  Called back and the automated message advised they were a travel agency affiliated with a company who's website I had visited and provided my info.  If you listen to the message long enough (total call time for me was 43 seconds) it gives you the option to remove your number from their list.  The option was # 2 and the following message advised it could take <insert # business days>.  I didn't catch the exact number.

Took the call from them today.  It was a recording from a travel company running a promotion, telling me I "won" a trip to Florida or something like that.

Missed a call from this number this morning, caller didn't leave message.
