Tickets Plus Posing as The Frank Erwin Center and charging enormous add on ticket fees, Internet

On the landing page, it states that the site is owned by "Official Online Tickets", and there's a disclaimer right underneath this disclosure that states the following:

"We are an independently owned and operated site specializing in sales in the secondary market. We are not affiliated with any primary website, venue, or box office."

If these disclaimers were present when you ordered, then it's your fault for not noticing. Granted, it's pretty easy to tell that the operators of this website aren't doing anything more than what is absolutely legally required to differentiate themselves from actual venues and official ticket distributors, but the onus still falls on the consumer to do their homework and ensure they're shopping smart on the 'Net.

If they weren't there, I'd talk to an attorney. (Preferably one that you trust.)

In either case, you can best exact "revenge", so to speak, with a little public pressure on the venue to stop using the ticket vendor in question. I have found that a letter to the editor of your local newspaper or taking your case to local online communities is the most effective method of doing this.
