And I'm begging you too (and everyone else here) to please stop using this exchange. Stop sending coins to their hot wallets. Didn't you check for reviews? Didn't you search and find the countless scam complaints about them? If those were all your savings, you should have done extensive due diligence and withheld sending the ETH deposit until you checked, investigated and double-checked again.

This exchange is based in Russia. Resolving all these deposit issues will only happen if they lift a merciful hand and do something about it. You can't expect or get any help from Russian authorities. Current laws in Russia are unfavorable towards cryptocurrencies so it is unlikely they will make any effort or even prosecute.

Stop using this exchange.
