I financed a car for 60 months. 3 months in I was late and the lender HSBC let me move 2 payments to the end of my loan. They were bought by Santander, I reached the end of my 60 months made all of my payments and now they are saying I still owe 1900.00. They are saying interest accrued on the payments i moved to the end of the loan. I get that but There is no way i accrued that much interest after all of these payments have been made. Can I sue them for breach of contract? I have asked on 3 occasions for a copy of my contract and the only thing they can provide me is the front page of a letter i received giving the loan terms which leads me to believe when they bought HSBC they didnt receive all of the files.
