Calls constantly, no message. 3x in 3 hours today alone.

Never left a message, spoke directly to a woman. she claimed I won a gift card for $250, all I had to do was answer a few questions, age, where do I work, am I single or married?, She just hung up on me, if I won something where's the details? Why did you just hang up on me when I asked what company are you and how can you send me a gift card if you don't have my address? That's when she hung up on me, definitely a scam, looking for personal information to try to do something using all my personal information, very rude, unprofessional, never specified where she was from, when I called back it gave me a busy signal all 4 times I tried calling this woman/number back, BEWARE
