I've read this site for a while, and decided to quit lurking and post after the horrible experience I had this weekend...
Anyway, here's some posts I made starting on Sunday morning.

I'm one test away from my MCSE... At least I should be.
I went and took my 70-293 yesterday. First problem was although all of the test question would be on the screen, it didn't register. I'd select the answer and click next and it would say something about scrolling through the text and wouldn't let me proceed. I had to move the scroll bar even though it wasn't showing anything more!
Then sixty-three questions and two hours later I finally finish, clicking to end the test. Seriously like eight minutes later it comes up with their stupid survey. Yeah, survey, GIVE ME MY SCORE. Click through all that, then it grinds some more and it says "Congratulations, you passed. Your score is 782." Big smile on my face. Starts connecting to Prometric.
Hangs for ten minutes. The lady there does something to the computer. Nothing prints, I have no record of my completion. She calls Prometric who issue a ticket number. I promptly call their number, and even though it says open on Saturdays there is a message saying their office is closed.
So now my candidate history still shows "Pending" for the test yesterday. I have no record of my passing, no record of my score. Anyone else have this happen? I felt a load off after I passed, and now I have this other crap to deal with. You know what you don't need after worrying, studying and passing a test? Stress from the dang testing system!
Now instead of being able to relax for the rest of the weekend I keep thinking about if I have to take this damn test again... Especially since my score wasn't that great. (Stupid certificates.)
I guess Prometric decided I should study the source material some more!

EDIT: And Geez, don't get me started on their website. Their teamed 56k modems must be getting near the end of their lifespan.
And now the site is down for "scheduled" maintenance...
(And saying Prometric sucks isn't just because of this one incident, although it's definitely the worst.
I've been to three testing centers and have taken a variety of tests, and I never have the problems I have when using Prometric.)

Monday
31 minutes on hold and counting...
44 minutes on hold and counting...
55 minutes on hold and counting...
65 minutes on hold and counting...
About ready to give up. System doesn't say anything about expected hold times. Just repeats crap music and "your call is very important to us."
(But not important enough to hire more than two $8 employees to answer the phone.) Nice partner you've got there, Microsoft.
EDIT: A message broke in and said "Due to an emergency our office is closed" and hung up on me.
Total hold time: 70 minutes.

I called the local testing center, and they tried to redirect me to Prometric. I was hoping they would say something finally printed.
No such luck.
I'm just updating this because I see my topic is showing high in Google results. Maybe someone that can actually help will see it.
It's ticket S385718 if anyone is listening...
EDIT: Now the Prometric number answers with a message about the weather.
Not sure where they are located, but maybe every problem I ran into is related to the storm.
