Pratt & Whitney called and said I won the lottery. You don't have to pay back the money you owed before, but you have to pay personal tax. Has this ever happened?

What a coincidence, I've met it before, but it's not a phone call, it's a text message.

I was very suspicious at that time, so I immediately called the official customer service number here. The other party said that there was no such thing at all, and told me to be careful to avoid being cheated. Don't be cheated of money.
