Unfortunately I cannot give Xceltesting Solutions a 1/2 star rating. I signed up for the course, had to extend, and now that I've paid $39.99 to extend, it's not letting me in the system at all. "You've extended your course". Really? I know that. And the website says 24 hour support yet there is an "After Hours" message on the voicemail.
