Are you in the repair process (warranty acceptance) or are they arguing fault? What happened?
I have a thread on this and basically dji said "hey buy a spare bird from us without any of the components for $700 have a nice day...". My logs were on healthydrones for everyone to see before they started charging for it. Dji has my logs and video and basically the compass went crazy a mile or so out, over a half frozen lake in the middle of NOWHERE. It was calibrated recently and within two miles of the crash. Had no issues or errors prior to flight.
