Just a suggestion as I have had trouble with email notifications before also. Try using a different email address or if you have the option for a secondary, list that as well. People I was with on the island who had cancelled flights with AA did get notification as did myself with Delta. I would get some emails from AA but not flight notifications until I changed email addresses and made sure I had the notification tied to a specific flight.

I think with AA there is also a text or email notification listed on the flight itself, aside from your profile, and that needs to be checked also I believe.

I think SXMWendell indicated his online refund showed up within 2 weeks or so. I will ask him for clarification. He indicated the refund showed up "in about a week".
