Dunno, as I know he just didn't do it.
Maybe he refunded people, but I didn't see it.
I think there is some misunderstanding we'll need to clarify later on.
If there is some code the community has paid for it would be a good thing for us to have it available.
If the dev was too busy to work on it he'll probably would be available to refund, but as far as I know the community members involved weren't in direct touch with the dev.
