Atyorney General office should be contacted on payday loan fraud companies.

I plan to contact the attorney general office in my state, due to an online payday loan I have. When I started, they loaned me $500.00 with a finance charge of $150.00. When I spoke to the rep, she told me that I would pay the finance fee for the first 4 loans and after that, they start paying my loan down. I was told that my loan will be paid down, but they will charge me $50.00 everytime my loan was paid down. I called them sometime last month to find out my balance, thinking I almost was done paying it off. What I found out is that instead of them placing the $50.00 towards their fee, they put that towards my principal and charged additional amounts on top of that. To make it clearer. I got charged $150.00 x 4 - which were my initial finance charges. Then I got $200.00, $185.00, $170.00 $155.00, $140.00, $125.00, $110.00, & $95.00 taken out of my account. Out of all those fees, I would think $50.00 would be their fee and the rest towards principal, but they reversed it, so only $50.00 of all those payments were applied towards my principal. They got $2,060.00 out of me so far and are still asking for $130.00 to top that off. So, I'm reporting them to the attorney general office, so I can get a refund of max $1310.00. What do you think?
