I won the Lottery!

I received a call this morning from a "MR Green John" badge number 505USA, telling me I had won a pearl white mercedes and a cashiers check for $19,500,000 and then monthly payments of $4000 a month.  All I had to do was submit a check for $540.00.  He even gave me a passcode,when I told hm I didn't have the money he called back with his Gen Mgr  a Mr Richard White...told him the same thing and he said welljust mail the check and we won't cash it until June 1st, never stating when my "PRIZE" would be delivered.  Oh yeah they had Jamaican phone numbers
