How do I log in to guildwars2.zendesk.com?
If you need to get help from CustomService, you can start to create ticket from support page.
1. Top there is Support, choose it.
2. From support page top right there is selection Submit a request, click it
3. Then choose what is your problem and continue to fill your ticket. Remember, that you need to give that kind of e-mail address where they can contact you.
When you have got automatic email from there, you can use that email corresponding with those Custom Service guys. Do only one ticket / issue.
