I don't think that the customer support is entitled to do that.In fact in most reputable casino they give you the option to click for freezing your account for a certain amount of time until you fix the way you are thinking and you don't deposit anymore,I have never heard of some customer relations support representative blocking or freezing an account just because they deposit in succession,maybe if you withdraw in succession as they can become doubtful of how come someone is winning so often and to check thoroughly and audit your games.Even so if you exclude yourself for 3 weeks or a month,you can stay 1-2 days without playing and then you go and register in another casino once you release it was a bad move and as such self exclusion solves pretty much 0 things regarding gambling addiction.
