After completing the Advanced Verification, which is really tough for me as I don't own any active statement docs within the last 3 months and our utilities and bills weren't named by me, the withdrawal is still suspended. The support told me that my issue was already escalated to the right team.
Have they marked your verification as successful? Maybe they are taking time to verify your documents from their side. Anyway, the advanced level KYC verification was always there. That's not a new thing. I can see that you are already aware of the fact that such issues take time to solve. You have just shared your situation here, not complaining about anything yet. Still, don't be surprised if they mark your verification as failed after taking some time. Your address verification documents could be the reason there.
Certainly not a few complaints available, the team is busy checking, so the working day is quite ready and the case is in the queue, BC Game is a big casino so I think it's natural, more patiently waiting.
Usually they ask for work time for examination on weekdays, so it's quite patient.
The possibility of invalid documents can also be the biggest factor why veryification requires a long time.
