If I could give no stars, I would. Got a notification about event date change, requested a refund the same day, got a confirmation email but no refund. Spent at least 5 hours with various representatives on live chat and on the phone with no help. Their system is set up to avoid giving you a refund, it's like a loop - you submit the request, then get a generic email with a link that takes you to the same "submit request" form - and so on and so forth... Representatives either tell you they don't see you request (even if you have a confirmation email) or that you did it incorrectly (even if you followed their instructions step by step)... Finally got through to a supervisor who didn't even try to help me and basically told me to take a hike. No sorries, no trying to solve anything - they don't care about making things right. Worst customer service I've ever experienced.
