None can't be proof.

Unless there are some thread cases between the user who is facing the problem, a mediator who helps the case, and the casino statement the case are being resolved with the term (both of parties: user and casino confirm those). Everything in public thread, I been in Casino for around 3-4 years+ most of the times is about (online casino) and user who are facing more problems it's always from sportsbook user. Either:
- Regarding Arbitrage
- Or abused

However, I'm quite curious and what's the case ? I checking the email again. The explanation with simple brief:
- User place bet
- User facing restriction for the betting size
- User getting advice to play into other game provider
- He made withdraw and getting request to KYC (but he completed)
- In the end statement, he got message withdrawal was approved & getting paid
