I've called several times, I've submitted half a dozen webforms, I even submitted a "processing times" feedback complaint on the IRCC website. I've contacted my MP who is now also reaching out to IRCC. I think I've exhausted all possible avenues for reaching out to someone at IRCC, but always looking for more. Emailing the portal directly is not something I've tried yet. I would be careful with this though, as your file is supposed to be assigned to a specific office for Virtual Landing so if that step hasn't been done then emailing them would be pointless I guess and only result in more confusion.
Omg! Did you asked an agent to add a note on your application for the immigration officer to verify if any minor step between approval and finalization might have been missed?
