Have you tried to get a refund? This kind of remotely downgrading a physical purchase is an outrage.
Since I had some trouble with a certain model airplane store in den bosch, I know a thing or two about Dutch warranty law (and a bit about how it relates to European law; the Dutch one is more broad). Was a huge pain and cost me a ton of time and I didn't really have anyone who already knew the law or was willing to dive into it to double check my work (juridisch loket was also fairly unhelpful). Feel free, you or anyone, to shoot me an email if you have further or other questions on the topic.
