I got my email confirmation on Sunday the 19th. The email also states this:
If you have any questions or concerns, please contact the Local Organizing Committee (“LOC”) at [email protected]. The LOC offices are open Monday through Friday, 9:00 AM to 5:00 PM. Due to higher than anticipated volume, please allow up to five business days for a representative of the ticketing team to contact you.
You could try to contact them at the email address, if you haven't received a confirmation yet.
