My department delayed my viva and is being unprofessional. Should I report this? I submitted my PhD thesis to my department last August for examination. However, I found out from my supervisor that my department only sent my thesis to examiners last November for examination. So it took them about 3 months to get my thesis to examiners. Before submitting my thesis, my supervisor already has elected examiners to examine my thesis and they all agreed to do so. Thus, there would be no problem in getting examiners to examine my thesis. And crazy thing is, when I confronted the staff who is supposed to handle my thesis examination, she nonchalantly said that she was so busy handling something else and she apologized for purposefully delaying my viva because her plate was full. I was beyond furious to learn how unprofessional she is when handling my thesis. Now I am thinking to lodge a report to the Dean of my school regarding how unprofessional my department was in handling my viva voce. But then, I'm scared that my department will have their vendetta against me when they found out that I made a report. Another option is to lodge a report to the Dean once I graduate from the PhD program but that seems like a cowardly move. 

What should I do?
Complaining about this won't speed up your defense or get your thesis to your committee any faster. It will just make you disliked within your department. Accept the loss of time, do your defense, get your degree, and start your next job. Unless there are specific rules against doing so, take the lesson that when getting your thesis to your committee and scheduling your defense date, no administrator will ever take the issue as seriously as you. So instead of delegating something you care a lot about to someone who doesn't care at all about this task, you could do these tasks yourself and get them done under a timescale you like.
