Good Luck with future endeavours then!
If only you took the time to find a reputable casino that would not cause any hassle, you would have jumped free from this one.
Making such accusations won't be tolerated that I can tell you, I am sure the support team has some grounds for why they agree with the operator with sufficient evidence was submitted to the complaints team. Also the fact that you create new AskGamblers accounts does not help either as you went against AskGamblers T's and C's for creating new AG accounts just to submit complaints...
Also if you feel its unfair of Casoo or are unhappy with the outcome of the AG complaints team decision, then you welcome to contact the relevant regulatory body who holds their license which is Curacao.
