Castlepay Loans threathened to go to court and now they are going to have me arrested Michigan

I borrowed $1000.00 from this company they first printed up a paper that said my interest would be $700.00 then I printed up my loan agreement which I have that said now my finance interest would be $10,000.00 and that they would be pulling out $700.00 from my account instead of $350.00.  I have been contacted by a company NSFF that does not exsist and a phone number they leave is not a phone number that you can call them back. I stopped the auto withdrawals. I wrote to the company which they call Red Rock Tribal Lending and when I put in Castlepay Loans in the Better Business Bureau they say there is no such company.  They have a p.o box 704 in Watersmeet, Mi. I wrote to this company and never got a return letter.  Something should be done about these companies that do illegal loan's.  Like the others I needed the money to move and I had no choice but to borrow this money. I have other pay day loans and I paid them back but not like this company who is a big repoff.

Thank You for listening.
