Identity and payment checks can involve sensitive documents. A public forum is not a suitable place to upload a passport, bank statement, selfie, proof of address or account credentials.
If you need advice, describe the type of request, whether it came through the operator’s official account area and which requirement is unclear. You can explain that a document was rejected without showing the document itself. Ask the operator privately which field, date or format needs correction.
For Great Britain, the Gambling Commission publishes specific guidance about identity checks and withdrawals. Those rules are jurisdiction-specific, so say which country and operator apply to your question. Has the operator explained the missing requirement clearly?
