What is going ON?

I like the rest of you wonderful Daughtry fans has been on this computer since 9 a.m. trying to get tickets. Twice I have gotten through. The first time did nothing at all after I entered in my CC info. The second time it gave me a #. I was # 53. But still no confirmation. Now... I am going back on there and everything is different. It's not the same as when I first entered my info. So does that mean I lost my tickets or what. This has really been a rough day! I sat at the computer for 7 hours.. Still no confirmation and the box office wont give me any answers! If anyone knows what I should do.. Please help me. I don't want to be charged for every time I try to get tickets.. But It's my birthday and I want to see Daughtry more than anything in the world!!!!!
