Since lndrsn contacted me I asked in the etherrestoreforum if there is a current time window, in which those 40% refunds are beeing processed. Maybe we'll have an answer in some hours.
I dont really know what can be done with this, but the following wallet is the one, where my ETH got transferred to.
