Here is my experience with Kopterworx. Kopterworx sells DJI products and repairs them.
I had problems with my camera, so I sent them my drone for warranty repair. I sent them by mail packed in original package put in another box, with fragile and mail insurance. They repaired it and sent it to me. The only problem was blurry pics on camera, everything else was like new. I was very happy at the beginning with new camera, because whole gimbal was replaced.
So I went outside for test flight and found out that remote is not working after repair. Something was rolling inside of remote. So I called them and send them a mail and they didn’t answer. Then I wrote post on Facebook page. His CEO Matjaz Kranjcevic replied immediatlly with comments like it was working when we tested and stuff in a rude way. They sent Phantom 3 back with normal mail, without fragile stickers or insurance.
I called him next morning and he said it is rude to post video on youtube and write posts on facebook. He was very rude, he didn’t wanna hear anything about broken remote. He said it was a favour and he won’t do that anymore. I’m asking how this is a favour if it was warranty repair!! He said you will wait now for 40 days for repair, because you posted video on youtube. He was so insulted and said it is my fault and stuff. If someone should be insulted is me, because I received damaged remote. After that I sent him my remote back.
Now it is more than one week, nobody sent me RMA number and no one is answering my email.
That’s how they treat customers. They have poor communication, they are rude. They think there clients are stupid and they are acting like they are big boss. Customers spend over 1500 eur at their shop. He could just said send remote back and we will check it. Matjaz Kranjcevic communication is suitable for being manager of a junkyard not for real business.
Here is video of remote received after repair at Kopterworx.
