I purchased used car from a Dealer. Upon purchase the Dealers Buyers Guide Information Sheet for the vehicle stated a "service contract was available at an extra charge". I purchased the Protection Plan from the Dealer. This month discovered our warranty was not valid. We contacted the Dealer they informed me Nissan declined the warranty and a refund check was sent to our financial institution. We were never informed that the warranty was declined. I was never informed at the time of purchase that the warranty could be declined. The Protection Plan I purchased states "I agree that my Service Agreement is effective NOW". If you pay for a service does that not establish a legal transaction between (2) parties?
