How so? Did you submit a Support Ticket? If not, then you haven’t even begun the proper way of getting assistance from Brave Support. If you did, what’s the ticket number?
Well, first off, have you ever lived anywhere other than the UK? More particularly, do you have a passport or other ID that you might have submitted to Uphold for KYC/AML purposes when you created your account? If so, that’s likely you’re issue.
I’m going to copy/paste something I have provided to others, just in case it’s something you’re unaware.
Issue that has been occurring with a lot of people is a mismatch between KYC. Uphold sometimes can be content with just updating the mailing address and submitting those documents, but Brave isn’t. What happens is the API communicates between Uphold and Brave about your information. The crazy part is Brave staff can’t access it, but the system does.
So what could be happening is it’s seeing your prior passport for whatever country you were in and it’s telling you it’s an unsupported region based on that. Unless/until that’s updated between their systems, you’ll likely have this problem.
Part of the reason for it is because it’s an extra layer of fraud protection. It’s easy to fake a mailing address but harder to get official government licenses/passport.
