I recently purchased an item from an inworld store. When I unpacked the item, it contained scripts but no dress. I tried redelivery at the store but when you click on redelivery, nothing happens. I contacted the owner of the store via instant message and no reply. I've since sent two notecards to her describing the issue with absolutely no response. The dress was not that expensive but I paid for it and I would either like the dress or my money back. How do I go about sending in a complaint about a store?
