Denied winnings

[Guest]

My problem is that I had previously signed up to and deposited within the site health games owned by bear group ltd. during this time I had won and tried to withdraw my winnings of a total £23,500, the company had then after my withdrawal request asked for I’d and then denied me my winnings as they explained I was previously self excluded under gamstop which I had not known at the time of using the site, multiple times during communication the company has admitted fault but denied responsibility to pay out. I had then gone to IBAS to further dispute my case and they had decided against my claim although I believe this to partly be sue to there threshold of 10000 dispute. My question is where do I go to from here and where do I stand as I believe I am still entitled to the winnings*
