I was hoping that things would be done to your benefit in the end,but maybe you do not need to give up on this.You should try to contact their support on a regular basis,and also post on every forum,reddit,twitter,facebook and wherever you remember.I see you have some contact in Russia,so why not report this case to their authorities?Chance that it will do something are very small,but I would personally try to exhaust all the possibilities to find out the truth.
