american cash awards you won two hundred fifty thousand dollars and a Mercedes Benz kingston, Internet

The person with a Jamaican accent calls to tell me I've won a cash award. He gave me this number that is in Kingston, Jamaica.  I did not call the claims center.  They called back and asked me why I didn't call but please talk to the supervisor.  She had an English accent.   She said I had won $250,000 cash and a Mercedes Benz.  I would have to come to Las Vegas to pick it up or I could have it sent UPS.  Then I would have to pay $2000 for the UPS fee.  I told them I had no money but she said I would be rich in a few days.  I smelled SCAM big time and told her not to call here anymore.
