I was having problems with my Zenmuse H3-3D gimbal and was told by the DJI folks in CA to send it in for repair and that from the moment your unit is logged into the repair system your 4 week turnaround time will start.. I sent it to them by 2nd day delivery and it was received at their facility on 6/22/2014. My next email for them on 7/10/2014 said "Your request (35245) has been received and is being reviewed by our support staff". My first question is did they ship it to Hong Kong for the repair. My next question is what is the status of my repair? I have tried emailing Alex R the DJI lead technician but received a terse response that they do not respond because it takes time away from the repairs. It is now 8/14/2014 and I still do not know when the repair will be complete and since it is well past the stated 4 week turnaround I would like a response from DJI. Based on this experience I would say that customer service needs improving.
