Paid the diamond annual subscription. Enjoyed it until game freezes ruined play and then periods lasting over a week where simply couldn’t login! Customer service take over 2-weeks to respond to emails to rectify things which is shocking. Then they promised a full refund but paid back the wrong amount. So after 4months their appalling customer support has still not resolved my problem. I will never use them again. Lichess, chess24 or chesstempo are superb in comparison
