Email is the only channel and it reaches me rather than a ticket queue. I answer everything that is not automated marketing.
The most useful things you can send are a bonus figure or cashier detail on this site that has gone out of date, and reports of an operator here delaying or refusing a withdrawal. Reader reports are the only way I learn how a cashier behaves in month nine rather than week one, and a pattern of them is what removes a site from the ranking.
I do not operate any casino and hold no player accounts, so I cannot see your balance, release a bonus, accelerate a withdrawal, close an account or pursue a dispute for you. For a licensed Ontario operator, the Alcohol and Gaming Commission of Ontario is the body with actual authority. For an offshore site, escalate through the operator's own complaints process and then to whichever authority issued its licence.
I also will not supply tips, systems or predictions, because none of them work. If gambling has stopped being entertainment, please use the resources on the responsible gambling page rather than writing to me.
