in December of 2002, I have signed a 5 year (60 month) auto loan agreement. The payment book received was for 60 payments over 10 years (every other month instead of every month) under the same interest rate and payment amount. I made payments every other month according to the book. Five years later (after 30 payments), a V.P. called me from the bank to tell me that the book was printed in error. He apologized and kindly requested that we make a new payment arrangement. We agreed on the phone to pay the remaining 30 payments on a monthly bases. Now that I am done w/ the remaining 30 payments, a new VP calls me to tell me that I still owe them interest of over $2,500. He tells me that the other VP is no longer there, and that the verbal agreement made means nothing! What are my rights?
