A51 only ships within the United States and Canada. If you are in Europe, you should contact Philip from Grow Cologne in Germany, he's been selling A51 lights for more than a year now.
As for ignoring emails, that's just not true. Your email could have gone to the spam folder, or A51's email could have gone to your spam folder. If you are in the middle east, Asia, Russia, Africa, then you are not ignored, but flat out blocked from contacting.
The reason A51 stopped sending lights to Europe, is because of the custom's taxes and fees and customers refusing the package because of it and leaving A51 with the to/return shipping costs, which costs more than the light itself.
If you are in Europe, another option is
