1986 NISSAN 300ZX User Comment / Complaint

Talked to nissan usa about 1986 nissan 300zx, fuel injector and related hoses leaking. they told me to take the car to the nearest nissan dealership and they would replace the fuel infector and hoses as part of the recall id #95i006000 - fuel system, gasoline, fuel injection system. i took the car to town center nissan and was given an estimate of approximately $3,000 for repairs. nissan north america told the shop not to do the repairs because the estimate was for more than the value of the car. nissan north america then told me that they would pay me the fair market value of the car. now they refuse to do this. my car is still at the nissan dealership with no resolution. supervisor at nissan north america does not return calls and her mail box has been full for over 10 days so we cannot leave a voice mail message - what are we supposed to do?
