My friend had the same concern. I think that the first thing you should do is check your OSAP page (the Financial Report section) and see the amount of money that has been
released This is the money that has been sent out and it would have been the money that you should have received.
In my friend's case, a part of the money was a different type of loan that would either be deposited (if you have that set up) or mailed to you as a cheque
Hope this helps!
