...until they either resolved that too or paid the $300 fee in order to reuse those tickets you will not be happy and will continue to post about the injustice on the internet!
You've got to be pretty careful about threatening things like that as it is technically blackmail.
I read about a guy who'd had numerous problems with his BMW, and had created a website about it which he was trying to use as leverage to get BMW to replace his car - which was something like 10 years old, had no warrenty, and which he hadn't even bought from a BMW dealer. After a lot of grief BMW eventually pressed criminal charges against the guy for attempted blackmail.
