I hit some sort of bug in DJI's ordering system and somehow ordered two Mavic's when I only wanted one. I received a confirmation for one order, and received the Mavic from Shenzhen a few days later. Two weeks later I got an email saying another Mavic had shipped to me. I received it a few days later from some distribution center in the US. Both Mavics were charged to my credit card. I've been waiting weeks to get return authorization.  I don't want two Mavics.  How long should I have to wait for this?  

Has anyone contacted you back? if not you always can give them a call.

I would have just sold it as there still in demand

How long is a piece of string?

Did you send your request to onlinesales@dji.com? What's your order number? I'll help to look into it.
