I couldn't find one anywhere on the website, and the only number I've found through Google says it's been disconnected. What's the current phone number for customer support?
I don't think they advertise a phone number. It's a lot easier for them to jerk you around and take 2 weeks to get back to you over email. They also put the help.elderscrollsonline.com site on the slowest web host on the planet to twist the knife and salt the wound.
