Affiliate Marketing Secrets

When my mom and I went to the Ringling Brothers and Barnum and Bailey circus there were these people handing out cards when you walked in the door. I can’t remember if they affiliated with the circus, but they must have been if they were in the arena is my guess. They instructed us to fill out our name and number, and said they’d call if we won anything. Only my mom filled one out because the rest of us were under 21 (I’m 20 btw).
We got a call yesterday saying my mom had won an all expense paid trip for two to the Bahamas. They said we’d just have to pay the taxes. My mom didn’t believe them because she didn’t remember filling out the paper at the circus since that was about a month or so ago.
The lady that called left her name and number and told us to call back. She said we had a year to claim/take the trip.
No one knows whether to believe if this trip is real or not. What do you think?
Thanks in advance!
