I lived in Luxembourg for 4 years, which you have to order through amazon.de and is fulfilled by amazon.de, and I've never had any of the issues you describe. And that's with an average of 120 orders per year.
Use some logic before attacking: Luxembourg is only the size of Saarland (German state). Fewer orders and fewer deliveries naturally mean fewer problems.
How about you read before attacking? I said it's pooled with all german orders.
