I really don't think it's anything to worry about. I also still haven't received an invite or rejection from CTC. There seems to be quite a number of people in the same situation. I suspect we will be hearing back in the first few days of this week coming.
If you never received a confirmation email, I would probably give them a call tomorrow morning, won't do any harm. What does it say on your BA application page? Is the status of your application *Submitted*?
Good luck to all.
