Dear U2.com Subscriber,
Thank you for registering for the U2.com Verified Subscriber presale. Unfortunately, we mistakenly sent you a confirmation email earlier tonight. Contrary to the email you were sent earlier, we are unable to offer you access to the presale.
While presale access is only one benefit included with your U2.com subscription, we recognize that it is important to many Subscribers.
If you would like a refund of your subscription, please contact us using the Contact Us form on the Help page, and select 'Verified Subscriber Refund Request' from the dropdown menu.
We apologize for the confusion.
The U2.com Team
