Very unstable service in China!

The app claims to have more than 30 VPN servers, yet 80% of them doesnt work in mainland China, at all! The rest 20% works only sometimes, and the service are not stable. Sometimes the connection lasts only half a minute, sometimes it lasts 3 hours.
I have been a user of this app since Aug 2012, back then the service were at least stable, and therefore I subscribed for another year. If the app doesnt fix its server connection problems, I will for sure stop subscribing to it.
