They had my email address wrong in the AOR and I sent CSE about that and it was not corrected. They said the file was transferred to Ottawa. I called CIC, and the agent asked me to sent CSE again, I said I did and no reply after even after a month. And I told him I wont be able to get any updates if they request any additional documents from me and I requested him to check if he can see my email address.
Atlast he checked that for me and corrected my Email address after verification. (I was lucky I think- they wont usually do that)
You can give it a try and tell them you already sent CSEs and its passed 30 days if it did.
