I am still amazed at OPs sincerity. This is the first time I am seeing someone admitting to a casino for their wrong doings. Situations as this is very rare and I must commend OP for this singular act of being open to admitting his mistakes. Most gamblers do not waste their time remaining with a casino when ever they are busted. They move on to the next one without minding how much funds with the casino as longs as they have benefitted hugely from the casino. It seems the casino are not bent on releasing the funds in their custody to OP as they already told OP to do the needful by returning the proceeds from OP wrongful act. I think the casino is more strict on their policy and for the fact that OP already signed their T & C making it more factual that OP did know he was wrong in the first place and continued with the act till he was busted. OP should keep trying and see if they would have to reconsider their decisions.
I don't know. Op could be putting on an act in a last ditch attempt to try and recover his funds since it's really difficult to trust anyone these days(Especially random people that you meet on the internet).
Op probably has a 1% chance of recovering his funds which is why it would take a miracle for things to work out in his favor.
