I can't blame the user for saying this is a scam. I tried to use the app during the trial period on Desktop (Mac OS), but it never worked. I contacted support to get a refund since the app was buggy, but they only gave unwanted and not useful answers. Now they stopped replying and are unwilling to help. They told me that I needed to start the refund procedure from the Mac App Store, but the thing is that their app IS NOT inside the Mac App Store. The app download for Mac OS started directly from their website, not from the App Store, so obviously, Apple can't manage the refund, contrary to what they say. Just don't use it and don't pay any subscription, there are a lot of other services (at the same price if not lower) that are way more professional and safer and, most importantly, working! Don't give money to this company, please.
VPNHub is a scam IMO. The advertise a 7-day free trial, but immediately charge your credit card for the full year. The client has compatibility issues with Windows 10 October update and they don't provide manual settings. Support is outsourced and horrible. Lastly, cancellation within the free trial does not result in a refund of the full annual fee charged at the start. There are many other VPN services that provide a better client, support and service.
