Now that I think about it, why would they ask me to verify my account if it was already verified?
Well there have been cases of account being sold or false documents being used to verify accounts and if a user is asked to re-verify his/her account is unable to do it or does it but this time with a different document or the details of the old and new documents doesn’t match it would mean that either the account changed hands or a forged document was used initially for verification purpose.
I have seen other reputable gambling sites asked their users to re-verify their account so this shouldn’t be a big deal for you as long as you’re not doing anything wrong.
It's not about the question whether or not it was re-verification, as I have provided the documents required from me.
It's about the wording after attempted verification (documents were used to verify another account) and after that, my account getting closed with $1.5m in it. If it was tied to my account in first place, it should've submit the documents to Sumsub, not receive this output from them.
