Payment canceled after waiting for 30 days

I requested a withdrawal of €500 more than 45 days ago, even though my account is validated. On April 4, it was canceled.

Here is "the reason" :

"We would like to inform you that your withdrawal has been cancelled by the payments department and the amount is available in your account.

Furthermore, the withdrawal option on your account has been temporarily suspended and your account shall be reviewed by the relevant department for security reasons.

We kindly request your patience as we are not able to provide you with an exact time-frame."

On April 10, I reasked the bookmaker but still no concrete answer:

"As the review of your account by the responsible department is still in progress we do not have any further information to share at the moment."

Help me, please !!
