I did. The response:
Hello there, unfortunately, we are unable to verify the validity of tickets that have been purchased through unauthorised third party resellers as we cannot confirm whether or not they've been onsold more than once. The best advice we can give you is to get to the venue early, as it will be a case of first in, first served. Hope this is helpful to you.
Wow. I read that as "we don't care, we have our money. Good luck in beating the other 30 people who have been sold the same ticket."
Wow, I can't believe they are offering that advice!.Isn't this why we have consumer laws, to protect consumers?
