Can somebody from Shuffle, or affiliated with Shuffle ask them what they still need from me in order to let me withdraw my deposit, like promised?
Have you in any way contact Little mouse explaining to him? If your case are true or legitimate then I will advise you to contact him to help passed the complaint to them because he is handling their campaign here on the forum, and I think they will honor him so easily if he sent your request to them.
You are right, and this is a very good idea actually, if there is anyone on this forum that has the power to help, it's Little mouse, so, yeah, I will join my opinion with yours advising op to contact little mouse, possibly the management of the casino will have a change of heart after little mouse plead on his behalf.
I used the word "plead" there because even with Little mouse speaking up for op, that does not justify that what he did was right in any way, what he did was as good as stealing from the casino. What ever they casino make him go through before allowing him to withdraw his balance, he totally deserve it, any other casino would have just confiscated the entire balance on the account and close the account permanently.
