Agreed, I would not write off AirVPN because of one bad experience. I have used AirVPN for a while and it has been a stable experience and I would recommend them. A few times a year they have nice sales going and the prices during these sales are very reasonable for the service they offer.
OP was disrespectful towards tech support, personally blamed a VPN service for not knowing the basics on how to operate VPN, then wrote a bible with a lot of useless information in a desperate try to justify himself.
