sadly i can not contact the GW2 support because their site has an error.
After some months i wanted to play GW2 again for a bit and they want my game key now.
No idea where that has gone, but im sure i dont have that key anymore.
Im also sure about im totally upset on that behavior, playing it for years without issues and now that
Arena Net can totally pollenize themself, deleted the game and will never support them again.
