i would hold on for an admin/founder but most likely they will say no Refunds The packages you can buy on this shop are virtual and don't have a real equivalent. Further more you get direct access to them and you can't replace them or the time taken, this means there will be no refunds granted.
I asked Mrwisski and he said put a post on the forum because the server i am on is being reset. He said they might be able to give the credits back.
yes you will get the credits back. the thumb rule is about purchases during the last 2 weeks before a server reset.
