south beach bartending school SCAM. Took my money, lied to me. hollywood, Florida

Today they called me and told me, i would be working at the Hardrock hotel, if i gave them a 100 dollar deposit.  i went there and they got my information, and asked if everything was right, not showing me the paper, then said since everything is right sign here. So i did.  I get home to find out it cost 600 dollars. and the paper i signed was a payment plan. Yet they never told me it cost more then my 100 dollar deposit. they never gave me a copy of my payment plan. or anything like that. and when i asked for my money back they told me i signed that i couldnt get my money back. I keep reading online now that they are a fake, and illegally ran business.
