Complaint Review: tickets-center.com

I thought I was ordering tickets directly from a venue. Tickets-Center.com tagged itself on. I ordered 2 Johnny Mathias tickets which should have been around $300.00. When I got the final bill it came to $609.00! Unfortunately, after accepting the seats it asks you for your credit card. You do not see the final bill until its all done. All sales are final. No refunds and no returns. In addition, when I did get the tickets I called the venue and they said that these are e tickets that can be printed out many times. Meaning that the company can sell these to as many people as they wish. Therefore, these are not guaranteed tickets!!
