Winners International Las Vegas This man is trying to collect $100.00 off of me for some kind of winnings Las Vegas Nevada

I had a phone call out of the blue from a man whom said he was with winner's international in las vegas nevada. the phone number he used is a majic jax phone number. i called the las vegas number and it was a majic jack number as well. he called this morning and said he needed to know if i had 100.00 in order to get this sweepstakes winnings. i said i don't have the money to get this and he said i must get it today. i said can we do this next week but he was persistant in this only giving me an hour to come up with the money. i left him a message stating it was kind of phisy that i have to pay money to get something i have won. i looked up the company on the internet and it seems there are more complaints than actual winners.
