Air Canada (Spoof/Imposter)

Type of a scam Travel/Vacations

I received a called from Air Canada Vacations, they told me I was chosen as a winner of a recently signed offer, which is true I applied for an offer couple of weeks ago, they were asking me many Yes/No questions, I did not give them any personal information but they hang up as soon as I said yes, to the question, do you have a valid credit card when traveling.
