AMP warranty misleading

AA warranties are misleading. My car went in for fuel gauge that is not working. Claim were sent in by Ford and AA did not approve the claim. The fuel sender unit is faulty and that is the cause of the gauge not working. Phoned the claims department and they said that it is not part of the covered parts. In their policy wording they do not state that this part is excluded from the list. The consultant that I spoke to said that they do not specify every item that they do not cover, just some of them. They are misleading their customers and when claims come they do not approve. Why pay for a warranty that you can not use? Completely useless warranty.
