What amazes me in your trouble is that Leaf doesn't stand up and help you out, maybe offer you that you could to send the back straight to them....
I've got some help from them. They eventually helped sort out the pricing with the first dealer and recommended me to return there, but I don't want to since they do not actively work with Leaf products any longer, and don't know Leaf gear very well and do not have the tools to do basic repairs -- all of which is important to me, especially since I'm using older gear.
Leaf's hands are a bit tied though, and I understand them. They cannot start going behind the backs of their own dealers, dealers would not be happy and the whole dealer-centric business model would start to fall apart.
My guess is that business is a bit too small and fragmented in Europe so a smaller brand like Leaf gets attention from part time of one person at a company which does whole lot of other stuff too, and then things tend to become a bit dysfunctional.
I'll try to have some more patience. It felt a whole lot better hearing that there are others that have experienced similar things, I was getting a bit paranoid and thinking that there was some policy to ignore people using old gear and/or gear bought in the private market, but it seems like we are all ignored like equals
