Casino not paying

I made a withdrawal 12/05/21 and still not received my winnings. ( x2 £2000)

I've sent documents, proof of how I can afford the money, bank statements etc and 2 months and 2 weeks down the line I'm still waiting. I get the same copy and paste email when I try and contact them, their website looks to no longer exist, phone number doesn't work. I think they are scamming people out of money. 3 days they said I would get my money. It's been nearly 11 weeks. Excuse after excuse. They blocked my account after I withdrew. No reason at all, customer service is terrible.
