Winnings held up with no response from support

I signed up on this casino last week, started playing and after playing for an hour there was a technical error in Sun of Egypt game. I was playing my free spins with 10€ wager when the technical glitch happened. I have attached the screenshot of the error. I had already won 180€ in free spins with more free spins to go. I thought the glitch was temporary and tried to reload and play again but no success. I reached out to the online support and even after trying all the measures they mentioned the glitch was still there and I couldn’t get my winnings. So I waited till next day and then contacted the support again, they said the technical issue is being resolved by their technical department and will get resolved asap. Nothing happened for couple of days and then I was chasing them again and got the same default response that their technical department is looking into it but they can’t give any idea of when it can be resolved.
Till date I am trying to contact them with no proper response apart from the default one where they day their technical deparyment still hasn’t resolved the issue.
What should I do here? They obviously don’t care about player’s money!!
