An offer was made to renew a repo contract. If I pay good faith money before aug 30 they would pay off old contract and restart new at new lower $.

I made good faith pay of 2 payment of the lower pay and they were accepted and cleared bank by aug 29. The contract they sent was dated aug 30, and said when they received payment by the 31st they would pay off old account and when they received 2nd good faith payment they would start new account with new payment book. I called and said you have received and cashed my good faith payment I am requesting updated contract reflecting my payment and why does my account show a balance of 154.00. The lady says you have to sign. I said no mame I want an up to date form she say that's the way you want it then. I said yes. You've accepted my payment. Yesterday I received a bill in the mail for 1404.09. The new agreement was 28907.00 for 20 years @ 5.49 198.68 month. They took my good faith payment and used it towards the old bill. I had been in constant contact with them to work this out.
