Hi,

I'm afraid the decision taken by the AskGamblers Complaints Team is final and will not be put under further consideration. Please keep in mind that in case of a disagreement with this decision, you are free to seek further assistance on the matter from the relevant licensing authority responsible for the casino brand which you are having a dispute with.

Sincerely,

Stephanie,

Customer Support - support@askgamblers.com"

So I don't know the reason I have sent them full documentation, screens and explanation.
Waiting for bitcasino.io support from here, maybe they will help.
Thanks to the others for the support.
