I had the same experience. I emailed them and told them there is no row HZ in Sec 100. First they said no refunds. Then they emailed and said they cancelled the ticket and had not yet taken money from my account. Since that all tickets for Desert Trip went up in price a whole lot! $1k more. You may be able to get your money back if you get on it fast, before they actually take the money. They are associated with StubHub and seem to have sellers who promise to deliver something between row H and P maybe?. Or they are fake tickets. Desert Trip is not even shipping tickets out until September. So? How could you have already e-tickets? Sounds too fishy. Good Luck. Get on them NOW!
