You were not 'scammed' you just lost money.
Imagine this as paying a dealer you've come to be quite comfortable with for some blow stashed in his car about a block away from you. As you are waiting for him to get your stuff from his car, some random patrol car stops by his car, notices the baggies in his hand and he is picked up on possession charges.
Did the dealer scam you? Nope. But you just lost money.
This is a semi ridiculous and implausible scenario, but it's the best analogy I can make up now.
