There is not a main email address or phone number listed on the WOW support page. Instead, they suggest going through their frequently asked questions and answers first. It is easy to search through the questions and find the answer needed.
Anyone that needs to speak to a representative due to issues with WOW first needs to submit a support ticket. They choose from categories like "Technical Support" and "Billing." The player must enter personal information, like their log-in ID, and the information about their current issue. Support gets back to them with instructions on how to get in contact with someone that works for WOW.
