Bastards. They supposedly deal with supplying used engines from Europe. I sent a 50% prepayment of 50,000 rubles. A day after they received the money, the scam started: they said there was no engine for 100,000 rubles, only for 180,000 rubles. I requested a refund, but there was no response at all. The company is registered under some criminal. The only way to contact them is through a call center. It's unclear where they are actually located. Now it's only the police and court for me.
