What happened with the elixirs and dolls is actually the reverse - players exploited the number of Farmer Elixirs and the number of Dolls involved... so it's not a refund situation.
Case for a refund would be, for instance: you lost a Doll but failed to gain access to the zone, or if you used an Elixir and didn't get bonus points, etc.
Not the other way 'round.
