It's ridiculous, those VPN are really annoying but not all of them behave that way. The suggestion is that turn your IP address from that country to another it may work because I tried it and it worked for me. But if it continue the same way please delete such VPN and download new one use
From your topic and the reply I see it to be normal for VPN to behave that way and I see it to be recent challenge. I have friends that open their account without any stress from VPN.
