You are obliged to approach your employer and draw his attention to contract breeches on his part. Then ask him to take immediate steps to resolve the situation. Have a witness with you when you do this.
Only in the event of you and your employer being unable to resolve the dispute should you approach SAFEA, and as a last resort.

That's right and as you can see from the OPs posts he has already brought the situation up with his employer on more than one occasion without a resolution being found. Therefore, he should seek to involve the proper authorities.

You might be right in regards the universities reaction to a perceived threat or loss of face. Again, it's a case of weighing up the pros and cons of your actions. I would say that if having registered a complaint about the standard of housing to the SAFEA a teacher is then fired for poor performance it would be much easier for that teacher to then lodge another complaint about wrongful dismissal and land the university in a spot of trouble. The other thing for the poster to consider is whether the actions he has already taken (multiple complaints, posting negatively on forums, etc.) might be sufficient enough for the university to label him a trouble maker and get rid of him anyway.
