Silvenora review for Pinterest

I just downloaded this app and haven’t taken any action or provided my business details or payment information yet. I left it to work on my store and returned to it after a few days. Now, they’ve deactivated my account without me doing anything. I emailed them to ask why, and they said they need to confirm my card payment. What card payment are they referring to? They’re also asking for my passport information. What is going on?
