It's virtually impossible to communicate with IRCC. If you use the telecentre, most of the time you can't get through. When you do get through, they tell you that they can't really say much; they're not very much help. If you use the web form, a lot of the time you won't get an answer at all, and if you do get an answer, frankly, it's gibberish and it doesn't make sense a lot of the time. When it does make sense, it's just a canned response.
There is no individual you can contact. They have put up a complete wall around all of their communication so that it impedes you from trying to get a hold of somebody who might know the answer or be able to help you with the problem that you're having.
