Okay, here's the deal.
Amazon was wonderful in that they kept contact with me to make sure I was being taken care of by the retailer.
The retailer, Koozam, did respond to all emails in a timely manner. Most however were saying that they needed a couple days to arrange the return and were trying to contact DJI. It actually sounds like the dealers even have problems contacting DJI. In the end, I was the one who got all the authorizations and did the work.
Surprisingly, I received an email from DJI in China saying that the battery had a bug and to return it to my retailer. My guess is that DJI knows that the batteries are a problem but have no clue how many are out there and so just accept it. I forwarded that DJI email to the retailer. The retailer responded immediately authorizing return so they must know the person who emailed me and accepted that as authorization. Shortly after, I got an RA number from Amazon along with a mailing label.
I FedExed the box back and after it was delivered, I followed up with Koozam and they advised that they would credit my account immediately upon notification from their receiving department. Not sure how big Koozam is but anyhow, that's how it went.
So far it's been a big pain in the butt however it has been satisfactorily handled. Of course, I'm still waiting for the credit but I have so much documentation at this point from every party in the chain that I don't worry about my CC company seeing my side of the deal.
I'll let you all know if anything else goes awry......
