John Deere Ins. oops last post

My company had the guts to tell us that our ins. was changing two days ago. This came as a complete shock to all of us. They are doing it to save them a few bucks. I was already set up with a surgon and not to my suprise, the surgon is not covered under the new ins. Matter of fact, I don't know if my surgery is going to be covered at all. I'm so mad that I can't even see straight, still. Has anyone had any luck with John Deere?Any help would be appreciated. Carol
