This is really frustrating if he always get denied even if he submit his details. Maybe the best thing he could able to do is to ask the assistance of support about what they really like since maybe they can share some formats to follow so everything ask will be submitted successfully.
If there's no able to guide him since sometimes support answer takes so slow then I guess much really better to contact them in this forum since maybe they can get the answer that they want to get from them and solve their ongoing issue. Hopefully both parties will settle and no person aggrieved in this situation.
The support already did give a specific ID requirements since his drivers license and other ID is already denied. The support is now asking for the OP passport as the only ID requires for KYC verification based on the screenshot provided by the OP.
I’m not sure what’s really the problem on his valid ID that he submits to the support but maybe the ID is already not in good shape or his case needs further verification to check his nationality that’s why support becomes stricter on his verification process.
