My husband and I took our children to the Dinosaur show and the raffle coming into the door was to win a free Trip to Orlando.  Both of us "won"   However when telling us we won, we needed a credit card and all this other stuff.  it is a scam. It is a way to get them to get our credit card number   .   Have them remove you from there list because they have called us about every 6 weeks and tell us that we won.   I have reported them to the District Attorneys Office of Maryland.
