I purchase a drone and it came to my with two of the four propellers not working and the camra did not work. So I asked for a refund, now I am in an email battle with their so call customer support. They keep sending me to the murchant who has been unresponsive! I think group is the murchant and they should refund my purchase, if they want to represent bad bussness that is their issue, I want a refund and should be able to get it since the product does not function... Bad bad bad service
