Vertige

Hello A few months ago I bought dances at Henmations and around Christmas I noticed they have been replaced (ip replacement). Of course I contacted henmations support, sent a notecard to the creator and no reply ! I don't have a proof because I never thought such a thing could happen, and I never thought to save my transaction history. The only thing I did is screenshots of these folders (dances replaced still have the good name of the creator and rights copy/modif as I purchased them. Not sure it was very useful but... Is there something to do to get my dances (or my money) back ? I'm very disappointed of the lack of support from the store, I purchased dances from them because the store seemed reliable...
