Something like what you describe has to be a scam. Unfortunately, too many people, particularly seniors are easy prey. Just think about it. Why are they asking for money? Why a money order? Did you enter a sweepstakes? Don't fall for it.
It is impossible. Don't believe them, they just want you to send money to them! Think about it, one person 19.99 dollars, if there are 100 persons who believe what they said, they can get 1999 dollars! It must be a fraud.
If it's in your email, let your internet provider know. If you received it in the mail, your post office wants to know/have the letter so fewer people will be affected.
