I can not withdraw

I placed third in a tournament that ended on February 9th, but I still haven't received my prize money. What's more, I haven't gotten any replies from the organisers even after sending them emails. What should I do about this?

I deposited many times into this casino my account is fully verified I deposited and wagered my balance x5 I won £3360 euros I am trying to withdraw 500 euros live support is stating I was sent an email regarding proof of cards I have not received any email from them the last two cards are old cards which I lost the new card which is related to the same account which I’ve deposited with I have shown them as proof I have also shown them proof that the two old cards were stopped and replaced by my bank account. I have sent them all the documentation they have asked for but I am not receiving any response back from them live support is saying there must be an issue with my email address but I am receiving all the promotional emails from them and emails from my personal manager. Before I deposited I asked live support is my account fully verified for withdrawals. They state yes which I also have proof of in my email address < email removed > could you please help me resolve this issue please.

Their website specifically says it takes 24 hours to complete verification. I have not received any request from the finance department requesting anything. I have emailed them and sent all proof of everything they are not responding. I have never experienced this before. Also they are not responding to my emails when I send them documentation to for kyc so I can successfully withdraw. Another point I would like to add is the casino live support team are stating that they sent me an email on the 6/6/2025 requesting documentation of my cards however I have not received any correspondence from them only promotion email and emails from my personal manager. Therefore it’s not only a withdrawal issue it’s also an issue of me not being able to complete kyc verification properly.
