Wir Wetten Casino - Support does not answer more than 4 weeks and remaining account balance is retained

The website www.wirwetten. com is not available to German customers anymore.
However, I still have a balance in my account of 53 euro but I cannot login to my account anymore as I am from Germany.

I contacted the customer support several times via email (1st time on 2021/06/05) but I did not receive any response so far. I also contacted the customer support of their affiliate system who answered only one time but I did not receive any further response when I asked for further support how to withdraw my remaining account balance.

My account is already verified and I have received payments in the past (last one in September 2020).

Now, more than 4 weeks have passed since my contact how to request a withdrawal but the customer support did not answer. Consequently it looks like the casino went offline (for German customers) and remaining account balances were retained.
