Canon 5D Mark III Joystick Failure

Earlier this week I had my 2 month old 5D Mark III around my neck while walking around the boardwalk on Coney Island. At one point I pulled the camera up to take a shot and noticed that the plastic nub was missing from the thumb joystick. I called Canon service earlier today as a CPS member and was told that I'll have to send it in and I may have to pay for the repair. I told them that a nearly new $3500 camera should not be losing pieces of itself while hanging around my neck while I stroll a boardwalk on a summer evening. So I asked for a manager because there's no way that this isn't going to be covered under warranty. After talking to a nice woman named Samantha for a few minutes the final result is that they've emailed me a pre-paid shipping label and if the techs say that it's not covered I'm supposed to call her and she'll see what she can do about it. I guess that's the best I can hope for considering the fact that they're taking me at my word and haven't seen the camera yet, but I'm still a little worried. Will keep you all apprised of the status.
