Received another letter from them today, same info about interview being held at the end of September and beginning of October as Skyseeker95 did receive, and also they say that: Subsidised fees for 250 on type hours will be charged to successful applicant.
Also they told that you have to pay 24 000 USD for TR on A320 or B737 and 20 000 USD for TR on ATR 72.
All in all I think its now clear that all this thing is a big scam and we can forget about them..
