Why does this thread read like it's all written by one single unsatisfied customer?
Writing anonymous posts on this forum is just slandering and hate talk, without any reference how much of this what you're writing is true, and you take away an option to tell the other side of the story (not your's only)...
If you're so unhappy with them, then use your personal FB profile, expose yourself and make a review there.
This way others can truly believe the words you have written, because there is a face and a name behind these words, not just a nickname and the "I'm new here".
Plus, they also have a chance of telling their side of the story... because of you and your opinion (true, not true or partly true), they might experience business shortage, which could have a negative impact on other existing students, that are satisfied, some of them might even be your friends, if you even genuinely was a student there.
