I have been using astrill vpn in China for over 3 years now. However this past year Astrill vpn customer service has been just awful.
they have even insulted their customers in some angry rage. (see attached photo). Their vpn service has not been working properly for the last 3 months. You can't connect via their own software and the alternative software only connects to the vpn for 30 seconds.
If you need a reliable VPN in China Don't use this company. I have switched to another VPN in China and no problems.
Reason of review: poor quality and customer service.
I didn't like: There vpn services.
