2015 Sportsman Touring Ball Joint Issue

Hello,

I purchased a 2015 Touring 570 new about 3 months ago. A couple weeks ago while riding down a dirt trail the front left wheel basically came off. I was going about 30mph but luckily was able to come to a stop without incident. I took it to the dealer a week and a half ago and have finally heard back from them that they aren’t ordering parts until Polaris approves the claim – they think that it will be denied because "ball joints don’t just come apart". I didn’t hit anything, it only has 230 miles on it and 200 of those miles are dirt roads not even rough trails. I am uploading three pictures, one of them shows the trail leading to where the ATV came to rest, I took this picture on the advice of the people I was riding with to show that I didn’t hit anything.

Any advice for how to deal with Polaris if they deny this? I honestly feel like they should be saying sorry that came apart, glad you weren’t injured…instead of what did you do to break it?
