It is interesting. I would have imagined that Amazon refunded it right away, with a free 2 months of Prime membership extension as an apology.
Most of my interactions with Amazon Customer Service has been nothing short of perfect. Just the other day, I called to complain that an item that was marked as "delivered" actually wasn't delivered at all. Within 3 minutes, I got a complete refund and also a free 1-month Amazon prime extension.
