I purchased under $30 tickets to the Jason Derulo concert for April 6th, 2011, and was charged $157.20 for two tickets that were in the $15-$20 seats. I contacted ticket liquidator who said that songticketing.com is responsible for the actual selling of my concert. All of these vendors / brokers need to be sued: Ticketmaster, Ticket Liquidator, and Song Ticketing. They all just pass it off responsibility to the next vendor or broker. Can anyone file a class action suit against these companies and allow for those who purchased tickets within the past few years to be part of this class action suit?? To add insult to injury, Jason Derulo only performed for 45 minutes!!
