Peltier Nissan

After purchasing the new vehicle, the f&i person told me my contract was not ready and to it pickup in a couple days, like a fool i signed a blank contract because he said that the department was closed it was late at night, when I picked up the contract the interest rate was different from what we had discussed and different from the worksheet he had wrote on he would not discuss the matter he was always unavailable on my visists to the dealership
