answered phone, then party on other end hung up after about 10 sec's

Woman called and I answered the phone she was laughing when I picked up, then apologized as she said she was talking to her husband. Without asking my name or giving hers, or identifying what company she was supposed to be from she launched into some spiel about how I won a vacation trip to Florida for staying at one of their hotels (she never identified which hotel). I hung up before she asked for my credit card info.

Caller identified herself as Emily.  Said she was calling because I stayed at one of their resorts.  She didn't say which resort.  I told her I have never stayed at any resort in my life, advised I'm on the Do Not Call Registry and asked that she remove my number.  All the while, she kept reading her script as I was talking and totally ignored anything I was saying.  I hung up.

Same as above.
