Payday Installment Loans and Fees

I recently, even though I should not have, applied for an installment loan with a company named bestchoice123.com. Now the amount was $725 which was deposited into my bank acct. The contract stated I would end up paying a total of $975 to pay off the loan. I thought that it wasn't too much, especially if it was going to be collected in payments of $237 every other week. I figured I would have it paid off in about 2-3 months. Then I really started to read the contract (yes I should have done it sooner but in a bind and single mother of 3 year old) and the RENEWAL fee, which includes finance charge, etc is $221 and per the customer service representative, I am only paying $6 towards the principal every payday...the Annual finance charge is 1260%. The company has an address of St. Charlestown, Nevis...I live in California. I already opened another bank account and am putting a "freeze" on my acct and making it a deposit only account, due to payroll purposes until I figure out what I should do.

Is this company able to charge me $221 every payday, making it $442 a month? Am I better off having a debt settlement company work with them or do I try and pay them with money orders instead? Any advise will help, thanks so much!
