If you were waiting for 3 weeks to get the new photo verified, then you should definitely contact them again regarding this. Don't wait for so long. They should always react within few days.
It's actually possible that they need you to send more money using a different payment method, because they weren't able to send you the winnings using the first method. That could also be the reason why you see your withdrawal being declined. For example some Mastercards support deposits, but players are unable to receive withdrawals to then, which isn't casino's fault.
Anyways, you need to start talking to the casino just to see what they need and why they need it. I also wouldn't send them any money if they didn't talk to you.
