I mostly disagree with above statements. MON project is relatively new system and most of Customer Care employees are French people trying to speak in English. I had called them twice during my CSQ stage and found them to be very polite and courteous. Lawyers are expensive and once they are paid they tend to be a bit unresponsive. Many times I have seen lawyers delaying CSQ related information ( for ex- ask for updated documents) to applicants resulting in rejection of applications.If you are calling MIDI customer care, be advised that they are just customer care representatives and most of them have little to no idea about Quebec immigration process. Do not trust their advice. You should contact someone authoritative in MIDI or use a lawyer to get a response. As far as my experience with the customer care people, they have no idea what they are talking about, they don't even know how the Mon Projet site works or its menu system. Most of them do not understand plain English or act like they don't. Honestly they don't care much about your concerns. So you should take some other course of action.
I invite others to post their views on this.
