I have not had any problems yet, though withdrawing every day multiple time, so I think the problem with you side, maybe locked for security reasons.
All what you can do, submit ticked and wait..

My account was frozen a few months ago. I contacted support. Took a few weeks to reply but was told if I secure my email address and use 2FA for signing in my account would be accessible. I have not made a recent withdrawal but have heard there can be problems with large withdrawals so may be worthwhile to make a number of small ones.

You can post on any crypto related forum. But only a maximum of 5 different forums to get paid.
