To be honest i can see where you're pissed off, i get it, but they have paid for it so technically it is "their" ticket, you know. Sure, speak to them and ask them if you can just pay them back for the ticket and sell it on to other people, but if they say no you can't blame them or do anything about it. I find gigs better when you go with minimal people anyway.
For the record, i wouldn't buy Muse tickets either, "best live band on the planet" or not. Just saaayyiiinnnn'
