I had a 1000 loan with castle and have paid them about 1450. My current principle is 750. I sent the letter on the site and asked for a refund of everything above the principal. They have offer to settle for487 and I declined but said I would accept a PIF. They told me I could request arbitration on their reservation. I told them no thanks and I will file a complaint with the Minnesota AG and FTC and my offer is off the rave, that I want every cent back. This is one of several payday loans I stupidly took out. My finances are a wreck. Does anyone have experience with CPF?
