Sold Faulty Watercraft

Purchased a Watercraft on July 17, broke down on us the same day in the water. Took it back, they fixed it, worked fine the second time, third time it broke down on us again. TOok it to the shop and we have not seen it since August 18. Watercraft is sitting at the shop, unprotected in the back, with salt water still in the engine. They do not return our phone calls and are not answering any of our questions. I would NEVER shop at this store again.
