CDI College review: Bad impact

I went to CDI College, Quebec city, QC from 2013 to this year. In the begining of my education, there were already something doubtful situations in the way the instructor behave. He spent a lot of time doing everything else than helping, and the most of the time, he doesn't tried to give an issue, an example, or something who could help solving problems that i encountered during my first course and during the few moments where he was at his desk.
I didn't recognise this institution like the way it was before. Each days was an amount of deceptions who grows up as the time goes by. So i decided to do the thing on my own without asking anything to my instructor, obviously, there were no answer i could get from him. As he spent most of his time laughing, and talking and talking, i silently study and did my home works like they asked me.
There had been a time where we moved to a small room while there were a complete construction works on the main place we used to be. This was the begining of an hell. We were almost 25 to 30 students in a space so small, that the sound's level got so high that it begin to be painful. Each and every days I was thinking : "What the hell am I doing in this place ?!". While some peoples were allowed to progress (being in the "protection" of this "instructor" especially for those who had education being paid by CSST, SAAQ, and other Big Financial Provincial Partner) Peoples like me were treated like losers, like uninvited guest, like wasted of time or pure fool. Strictness was high for us, while there were fun for others.
In 2014 i asked to continue my education during evening courses. I can say that the instructor was very good, and the environment was healthier than those ones i lived in 2013 but the worst was made. How many times i told this to my director, how many times i ask to have a solution, and each and every time there were a complete ignorance of the situation. I talk a lot about what i was living in 2013, but without any issue who came to a point where I was ask to have a meeting with two directors. I was surprised of the existence of one of them, i never knew that we had someone called pedagogical director. They told me that i was a half way of being rejected. They were giving me my last chance in this new commitment to make me study during evening.
I never never never been helped by one of them, i never had their so called "Solution plans", "Helping plan" or whatever they called it, never ! The only time they asked me to meet them was to show me how low i was in terms of results, in terms of progression, etc. I had work 15 years as programmer as well as computer technician. But the lack of help, the abuse and misconduct ways of my instructor who treated like a dump during 2013 went to unacceptable ways of evaluating what i did.
So, in every aspect of my education, i was the one who was always faulty. Nobody's fault but mine. Finally the direction decide that i could not going one further in my courses. I ask it would be possible to be in another course, nope, they asked me to get out of the school and to never attend coming back. I lost 18 000 dollars, i lost a part of my dignity, of my pride. I was break in pieces, and now I'm fighting nightmares and a emerging depression. I cry a lot till this decision, i have lost a lot in self respect, i don't know where i'll go, and for them, this is me the perfect loser.
