They have client area where you can ask for help, the only thing you will have to do is, you will need to complete 1 simple survey to get 5 days FREE VPN, I think it doesn't matter if you spend 2 minute to complete a survey and get 5 days full functionality vpn.
the most good thing is that you can ask for custom port either onudp or on tcp, that's even for free, and that's a good thing if a percular service provider block some particular ports..
Currently there supported ports are:
UDP
53, 1194, 80,
443, 8080, 55,
5000, 9200, 50,
Custom
TCP
53, 1194, 80,
443, 8080, 55,
5000, 9200, 50,
Custom
to use it free with Airtel use any UDP port, for reliance use your correspondence port which is free for you, since docomo's vpn trick has been banned you can check varities of ports to get it worked, same applies to other service providers.
