Covered or not

We were just denied a second time on our service contract with Good Sam. The first time, they denied replacing a broken step on our Tiffin MH. They did pay to replace it the first time it broke. One year later, it broke again. Out dealer, Vogt here in Ft Worth, went ahead and ordered the step and when they called for authorization, it was denied. That was $1500 on an item that was previously approved. Then last Nov, we took our MH to Red Bay for some repairs at the Tiffin repair facility. As of his last year, Tiffin no longer accepts extended warranties. So we called when it was in the shop and were told tus to send in the repair bill with a brief explanation. We did and again it was denied. They said we need to take our MH to a reputable service center that will call for prior authorization. REALLY! How do you get better service, especially for full timers, that at the factory. Very sorry we bought this Good Sam policy. We feel they are taking advantage of their customers and not honoring the spirit of the contract.
