I understand that it’s inconvenient that they won’t ship to your country, but they’ve not broken their promise and not delivered. Clearly, they don’t have a solution for you, and I’m not sure what you’d like them to offer. They’ve explained that they can’t ship to the Netherlands due to a technical error. What additional information do you expect them to provide? It seems evident that this isn’t an option and won’t be for the foreseeable future. In my opinion, this would be a clear indication to move on.
