LOL! I think this isn't an isolated case. Exchanges have always this tendency to be inconsistent. Nothing's surprising here. But if you're after your money's security, you better avoid exchanges which restrict you country.

You can deposit, trade, and withdraw until you can't and when you raise the concern, they can simply tell you that it's clear in their ToS that you aren't allowed to use their services, that you are in violation of their rules. As a result, your funds shall be locked. Easy money for them.

Don't even trust their chat support. I'm sure most of them didn't even read the Terms of Service. They're unfamiliar with the rules. They're just outsourced individuals who have no accounts on the exchange themselves and are working from faraway towns with minimum salaries. They can't even construct a proper sentence.
