i've been standby by my computer since… i've been standby by my computer since 7.30 am, to now, 11.52 am i wrote this review, the site is still like damn. Idk how many times i've log in into my account only to face an ERORR when i clicked the date for the exams or when i have reach the last step for payment. I refresh many times and the pages just give me 'tadaima, the traffic is busy', why bother make a cheap web.

Does not deserve one star Does not deserve one star. Website does not function properly, multiple attempts required to make a booking. Payment taken for a service that was not delivered. No way to contact company. How does such an abysmally bad company get big government contracts? It's an interesting question.

Not even one star Not even one star. I tried to schedule my exams and spots kept getting filled within seconds. It pushed me a month back so I quickly scheduled what I could. I called to ask if I could get in any sooner and I'd have to pay a rescheduling fee of $35. The only reason I scheduled it was to secure a spot to not get pushed back even further hoping they could make some accommodation. Also, they couldn't help me change the order of times I already scheduled same day without paying 3 different rescheduling fees. Very ridiculous. I'm asking for minor changes.

Horrible Service Can't believe CSI uses this terrible service. I logged in for my exam. Got my security check done. I waited for my proctor for over 15 minutes and no one showed, so I disconnected and tried to reconnect. Now it says my confirmation # doesn't work. Tried all the troubleshooting on Prometric website and after several attempts, finally got a person on chat who couldn't help me. They referred me back to CSI who says I have to reschedule my exam. And they wouldn't even do it right away. If you have other options, don't go through CSI.

The booking system is almost impossible… The booking system is almost impossible to wade through. It's like it was designed by someone that had never used a booking platform. Why companies use Prometric I'll never know. I tried to book an exam for one of my staff and ended up, after 30 minutes of circles, giving up. I'll be complaining to The CIOT about this too.
