On another forum, a Class1 official posted this:

Players with positive balance on their casino account are kindly asked to contact Class 1 Casino support on support@class1casino.com to be able to process their funds immediately.

So there is still hope for the players. (Which doesn´t change anything in my personal opinion about this casino and their politics off silence for 2 weeks)

I think I read somewhere that Playtech probably decided to shut them down because they operate in Italian market without their regulator's license, and Playtech most likely did not want to jeopardize their Italian business because of a licensee's unauthorized operations... Anyway, it's good that the crisis is being sorted out for the sake of us players, especially those with remaining balances in Class 1.

To be fair to Class 1 they always replied promptly to my e-mails and I got my cheque yesterday so thank you to Class 1.
