Hello,
As it says 6 weeks.
You applied on 22nd December, 2012 . Office was closed for Christmas and New year . That is why the process is slow. And today is exactly 6th week including the holidays week.
I will suggest you to wait for one more week. Then you can go to the Registrar office with your application copy.
Personal Experience- I applied for refund from Centennial College , And only on the 6th week i got my refund. So wait for 1 more week.
Good Luck
