I finally got through to the phone number and they answered the phone "Discount World Vacations"  I asked why they were calling me, and they said that I entered a contest "a long time ago" and that they were trying to give me my prize!  Can you imagine that people really fall for this?  Anyway, I asked them to remove my name from their list, which they said that they would.

I keep receiving calls from this number. The caller id comes up with the name "Discount World". It's always around 11:00am.  I called back and the number is always busy.

I wasn't available and they called 4 times using different numbers
