Titlemax Title bucks Ripoff by titlemax snellville, Georgia

I had some down times, so i decide to go to title bucks and get a loan. When i enter the building the first thing i saw was the sign that read we are here  to help you. I ask for $2,000 dollars ,they gave me $3,500, i ask the agent what was my monthly payment , she told me that will be that will be $361.oo which did not sound too bad. 11 months later i decided to check on my balance ,only to find out i was only paying the intrest on the loan, this is not something i normally do , i only wish the agent was honest with me  and give me a better understanding of what i was getting into . If i was told the truth i would of walk away or take only $2,000 which carry a lessor intrest rate, so the agent know just what she was doing maybe the bigger the loan the more incentives for her. now its december 2009 and i paid over $5,500 and i still owe $3,900 on my principle, this is too bad, i was told by the agent the only way out is to pay that amount in full or i will lose my car. can someone help me please ?
