I self excluded with them on July 12th permanently but because I know I still had some small bonuses waiting for me which i wanted to gamble with I asked them to reopen my account. For obvious reason they should have never done that, it's called player protection.
Betfury team is indeed guilty here for allowing you to play again by removing the self-exclusion from your account. They shouldn't have done it there by any means. I would have blamed you here if you created a new account and lost the funds. But the issue is different here. I'm wondering how you have requested them to reverse the self-exclusion. It will be better if you also add the screenshot of the email in which you requested them to reopen your account in order to play with the bonus.
