Jeff Hickman, Director of Customer Support, posted a quick note about the "Technical and Billing SupportHours for Memorial Day" on the Camelot Herald:

Here are the hours of operation for the Memorial Day holiday. These hours ONLY effect Technical and Billing (e-mail and telephone) support. Monday, May 26th, 2003 (Memorial Day): Technical/Billing Support CLOSED. Again - this is only in regards to Technical and Billing Support. In-Game support is not effected by this, and CSRs will be online and ready to help you.
