Red Rock Tribal Lending Payday Loan Complaint

Red Rock Tribal Lending Payday loan department,

Charged fees or interest I didn't expect Washington

I went on line for a Payday loan Castle Payday. They advertised that it would cost $200.00 to borrow $600.00 a total of $800.00. I paid them a total of $840.00 within 2 months. They sent me a email that they were going to take out another $210.00. I called them and they said that those payments ( - ) were for interest only. That I still owed them $800.00. That is CRAZY!!! Please help me, I do n't know what to do, I cant sleep I am so worried.
