Kingston JM scam

This guy called I hung up after hearing something about I Won.  He called back and was not happy I hung up on him.  So now I won all this money, he also wants two men to come to my house when FX brings me this check from Bank Of American so when I go to my bank they are there so I will not be robbed. REALLY?  Then told me I need to go to Walgreens and buy a Green Dot Money Pack Reload card for $290.00 something dollars. Ask me how far I live from Walgreens. Then call them back and give them the pin number. Told him I don't even have $20.00 too my name. Told me they would front me the money they would take it out of the money I won. Really. Dumb buts told me that was what I would need to pay in IRS taxes for the money. LOL.. Told I will call you back once I spoke to the IRS.. Just to be sure. LOL..
