What is needed for verification
Not all questions have the same answers, but the document list is short; below are four essential types.

Provide clear front photo; name and birth date should be visible for easier verification.
Passport
The photo and name must be clearly visible together; folded pages cause issues.

This may also work if the information is clear; if lighting is low, take the photo again.
Address proof
Sometimes additional documents may be requested; watermarks, cuts, or old copies should not be provided.
Keep messages to support simple.
Provide a short message with the issue, time, and account name; this helps the agent understand quickly.
If verification stops, reply in the same ticket; opening a new message will lose the previous history.
Provide a screenshot
The error image is most useful when sent with the message; they can quickly identify it.
Focus on one question
If you write many topics at once, it slows; send one issue at a time.
Include the time
When did the issue occur? The 10-minute window is helpful.
Match account information
Check name spelling, phone number, and birth date; small mistakes cause messages to return.
