you need to buy a spot on someone's VPN server... you don't just install it and go. not sure if that's what happened, but the way you described it... i think @ash is confused as well. ;)
another good (by reputation) and cheap VPN provider is NordVPN:
price isn't the only issue. you have to think about what country the VPN is hosted in if you want full security. it sounds paranoid, but why are you getting a VPN then? amirite?
Random Agent Spoofer is a useful tool for hiding your IP, as well as spoofing your browser fingerprint:
@ash and @peppernrino thank you very much both for your replies!
