They don't seem to respond to any email, but someone still is behind it.
After my login was not working anymore, it was magically restored, without any response whatsoever. However, my NMC withdrawal was conveniently "not processed", there is no transaction for it and it was deducted from balance.

Hello, guy out there, could you check the e-mails - "NMC withdrawal not processed". That's all, after that I won't curse at you anymore.
