Adam1222,
hitek0007, it might be worth calling Aeroplan and just seeing if they can do something about it. I posted
upthread about an even lengthier delay, and it didn't sound like it was ever going to get addressed unless and until I phoned in. Find something else you can do while on hold and worst case, you've wasted a bit of your time, best case they talk to ticketing and get it done in 5 minutes like with mine.
Just phone the general Aeroplan number and follow the prompts for flights and change an existing flight. When you get through, tell them you tried to cancel online but it doesn't seem to have gone through as you've waited a couple of months and still haven't gotten the refund notice.
