First Heritage Credit Bossier City review: Loan

I borrowed $1000, and defaulted on my loan. I paid $400 before I got behind. A judgement in the amount of $2005.19 was filled against me. I have since paid $1400 in payments to the creditor. I called to get a payoff balance and was told that my payoff amount if payed in full today is $4092.04. If not then a rate of 35.54% interest would continue building. On top of that the attorney they used is charging 25% interest on all owed principle and interest owed. At this rate by paying it out I'll end up paying over 10k for a loan of 1k. This can't be legal and I will be seeking an attorney to battle with this company.
