ID Verification rejected — no way to resubmit in Studio account

My ID verification was rejected on Saatchi Art (artist profile: hyunsillee). I checked the rejection email for the reason, but there is no resubmit or re-upload option anywhere on the Tax Information or ID Verification pages in my Studio account — the form appears locked after rejection.

I submitted a request through the Help Center on August 31, but I haven't received any response yet.

Could someone from the team please help reopen the ID verification form so I can resubmit, or let me know what additional steps I need to take?

Thank you.
