While the bickering might be entertaining to observe, You can't control how douchebags act online, you can't undo the previous service visit and "evidence" therein, BUT you certainly can take control of yourself, and through this, the way the rest of it plays out from now on.
I would definitely suggest you escalate the warranty denial through Mazda USA and even to arbitration if need be. Flagging the car in their system is a serious situation and will negatively effect the rest of the warranty that its left. During this process it is key that you try your best to act respectful, speak clearly and properly. No matter how angry you may feel you need to act cool as a cucumber while speaking with anyone at Mazda, arbitrator, judges etc... A reasonable voice and demeanor goes a long long ways.
Speaking with a reputable attorney couldn't hurt either.
Regardless of who you are, and what you know, they way you have presented yourself here in this thread is as a complete and utter asshole.....
the post about pistonreipper being an a-hole and your previous post go hand in hand
