Online rescheduling of NCLEX didn't work!!! I'm in no-show hell

So I found out yesterday that I am in a bit of a pickle...I registered a month ago, changed the date to a week later (as I was taking a Kaplan course and wanted time to review after it) and the computer screen said something along the lines of "your new test date is ---- at ---- location". But I didn't know that I did not get the confirmation email stating me new NCLEX date. I was looking up the test center directions yesterday and saw a "no show" under my appointment. I paid the $200 schedule again, but then read the fine print that no-shows ATT's are invalidated and have to obtain new ones! After bawling my eyes out I see that I can't do anything about it until Monday (why is a huge company like Pearson Vue not have a single representative in the entire US available on the weekends??!! This seems irresponsible on their end). I feel like such an idiot after being such a studious nursing student and checking everything twice, now I might not get my job (orientation is in a week) because I don't have an ATT, which means that I cannot sign up to take the NCLEX or even see which dates are available near me (when I "rescheduled" two weeks ago dates are at least a week out at my closest site).

Has anyone else had this happen? It seems like it should be my fault, but I was not sleep deprived when I changed the date and all I can think of is that my internet temporarily went off and the last little bit that was needed to tell Pearson to change the date didn't go through.
