It was not not the bonus term, it was one of the terms under 10. Collusion, misleading action, fraud and criminal activity from https://frankclubcasino.com/en/infos/terms_and_conditions i dont know which one or ones i broke and they dont want to tell or show me any proof which feels very shady.
I have no idea what terms i might have broken and since i have only been playing slots, im also down around 600 euros in total so im not even on a winning streak on their site.
EDIT: My money has been deposited from my skrill account and bitcoin wallet mostly from skrill.
