That link should be removed. You report bugs ingame in EU - can give you directions if you can’t find it. As for tickets, when you click on support, there’s a small link top right that says ‘contact support’. I guess they want you to read the appropriate articles first but sometimes there are things that aren’t covered. I would suggest https://eu.battle.net/support/en/help/contact/187/ticket and ask for someone to look into your character. Describe the problem briefly.
