I have got my self in a bind with "title-max"...I have been paying on a $1200.00 loan for 5 months at $200.00/month... Balance is still$926! Help!

I really did not realize how predatory this agreement was... I was shown an amortization schedule for 12 months prior to signing it, ...It looked reasonable, with the payments decreasing over the 12 months... We had no intention of going 12 months, but when we tried to pay more, we were told that the loan was only a 30 day loan, and interest and fees were added each 30 days the loan was not paid off. Please help me
