I tried signing up without VPN and gave up after a few days. Credit card verification succeeded but it seems they need to manually upgrade your account. Support couldn't tell me how long that would take (system said 24h but took longer). And once that was done, you still can't order because you need to increase limits. I gave up at some point and went with another provider. Has been a long time that I've encountered a system that takes several days until they allow you to spend money.
