Has anyone had any issues completing an equivalent exchange? A support rep named "Casey Zamora" at 3DRobotics had promised me an equivalent exchange for my rattling transmitter then just tries to file an RMA instead without addressing the equivalent exchange promise? I even have his statements in e-mail and I quote them in reply. However the quotes and links I give them are simply not addressed in response. Has anyone else had similar issues? How did you handle it? Is 3DRobotics support simply becoming another DJI? Should I just fix it myself and ignore the (seemingly worthless) warranty?
