Ray Huffines Chevrolet

We bought a truck from them in August that was suppose to be GM certified. Not even two months later now they are saying that the battery is no good and we need to pay almost 300 dollars to replace it because it is not covered on the warranty. How on earth does a truck pass GM certification with a bad battery. They are not even willing to pay for the part themselves. The truck still has dealership tags on it! The sales man forgot to order tag for the truck as well so we still do not even have license plate tags. This is just ridiculous and I feel as if we are being taken advantage of so they can make a buck off us. Every time we call we get the run around and no one will take ownership of the mistakes. Will never buy any type of car from any huffiness dealership ever again.
