I can agree with the slow speeds - that's something I have mentioned in my post here.
However I strongly disagree with bad customer service part - I have had a opportunity to exchange a few emails with their cs and with Yegor himself and must say that they were extremely polite and helpful - however this is just my own experience so it might be not representative.
Anyway, if I had to choose just one VPN and had to stick to it for the rest of my life, then I would go for Mullvad
