Casino is unresponsive

Hi I signed up to this casino couple of months ago, after depositing quite a bit and losing, my balance is now at 411 euros, and they started requesting documents about my crypto wallet and proof of funds.

I supplied them with 2 proofs of winnings from other casinos, these were declined because they were too old even tho they were from 2023, also they requested a screenshot of my crypto wallet with personal information.

I use a crypto wallet that has no personal info attached, they keep requesting things that are unreasonable. Also when i ask livechat what the status is, they just keep saying its been forwarded to the relevant department and that i will receive a response on email, but i have waited over 3 weeks for response on email yet nothing arrives.
