To UK-customerserviceteam@wmgcustomerservice.com , I added my order number from the preorder I did in the store. Good luck!

I emailed one of the links above in this thread, they replied within the hour and send through a code and I have now tickets! Hopefully you all have some succes as well...

Much of a panic, the pre-order started and still no e-mail, even though having received early access to the show in Nijmegen... Good luck guys!
