If it helps. At the beginning of November 2014, I got my money back for a "mining right" from the seller Menig. At the time I wrote with asicminer-shop.de via PM.
At that time, he was seeking a preliminary injunction against User Menig. In any case, User Menig has returned the money back to me in 03.11.2014.
I still have the bank statement and can send you or the admin a clipping via PM.
