So, I decided to call to follow up on my refund....after several different CMs, we were able to determine that my refund "fell thru the cracks"....so they put a rush on getting my refund, and I should have it in a few days.
The CM did confirm that they are processing them based on the date of your original party date. I had mine for Halloween night.
Anyway, it might be prudent to follow up by phone if you haven't gotten it yet, and you think that you should have received it by now. Also, it helps if you have the Confirmation Number, or the Magic Band numbers that the tickets were tied to originally.
