Sleazebags! If you order tickets online through Ticketmaster, watch your credit card bill VERY CAREFULLY. They will automatically sign you up for an "Entertainment Rewards" program and charge your credit card $9 every month. I called American Express about it and they were well aware of the scam. Apparently, they get calls about it constantly.
I called the Entertainment Rewards people and was able to figure out how to trick their voicemail into letting me through to a live person, so that I could cancel the program and request a refund, but I AM FURIOUS!!!
Naturally, I did an internet search and found out there are hundreds of stories out there like mine. How do these people get away with it without going to jail???
If you are planning on buying tickets online, DO NOT USE TICKETMASTER. Caveat emptor, my friends.
