If you go to the TicketZoom website in the bottom left corner you will see a 100% Guarantee. If you click on the about us tab you will find the following-
You will receive a 100% refund for any event that is canceled and not rescheduled. After receiving an order confirmation from our ticket network, if for some reason the tickets you selected were not available, our network will substitute comparable or better seats or our network will refund your money. All tickets are guaranteed to be 100% authentic, this is something that fan-to-fan and internet auction sites cannot provide. Speedy order processing and professional ticket delivery…you will always be on time for the event! All transactions are processed on a secure server with full 128-bit encryption. This means all of your personal information, including your credit card number, cannot be read as the information travels over the internet.

We ordered tickets from them Nov. 3rd, 2010 for a Dec. 12th football game. They promised the tickets would arrive no later than Dec. 1st. ON Dec. 3rd I sent emails telling them we had not recieved our tickets. On the 4th my husband spoke with a rep who said the tickets would arrive before game day but to call back on Mon. the 6th if we had not been able to contact the seller & ask to speak to a manager. When my husband called back today, Mon. Dec. 6th he was told that they have not been able to get ahold of that seller. We would not be getting our tickets & if we wanted a refund we would have to call our credit card company. They did not honor their guarantee in any way, not even with comparable tickets. Since other people were counting on the tickets we had ordered we had to go to another site & pay $80.00 more for much worse seats.
