I bought a 2008 nissan versa in November2007, I got extended warranty on the car, that was costing me$4000 extra. I bought the car for my daughter. Because she had no credit. Any way before the first payment was due I went back to cancelled the extended warranty. Sign the form, the finance lady took the package they send me in the mail. She told me it would take four to six weeks. And I should be getting a letter in the mail. Can you believe it now may 7, 2008 five months later, no cancellation. Received by nissan motor acceptance corp. When I called. The payment center they never received. Please help me. I already have new car warranty on this car. My daughter cannot afford an extra $4000 dollar. I am a single mother thanks you.
