JackpotCity complaint: refusal of withdrawl

I have been a member of jackpot city and other casinos in their brand for apprx 4 years now. In that time I have racked up a sum that totals over $50,000 in deposits, all in jackpot city alone,and nearly all of them made using vanilla visa gift cards as the deposit method. Usually my girlfriend and i split on a card and she uses her half on the casino of her choice,and i use my half on the casino of my choice,which is always jackppot city. Recently i won $2000,and was happily awaiting my withdraw. After waiting over a week,i started to email them to ask where my funds were,and out of nowhere they closed not only my jackpot city account,but all other accounts i have with their brand. When i inquired as to why,they cited that I had requested a self exclusion,which i most definately did not. Then they start telling me that i need to send them proof of ownership for the card. I tried to explain to them that proof of ownership is not needed for this particular card as it doesnt matter who purchased it,there is no need to register it before usage as it is activated the second you buy it,no regsitration needed,no names or ID involved,you buy it,you use it,you throw it away. And lots of times i havent bought the card myself,ive recieved them as gifts,hence the reason the actual name of the card is Vanilla Visa GIFT card. However,just to appease them,i went to the store where it was purchased and had them reprint me out a reciept,i then went online and registered the card to my postal code(which is unneccessary,but may be needed at some retailers websites),and then i sent them a screenshot of the registration,and of the transactions used with the card. I then explained to them why 2 people had used the card,because in no way anywhere is it against the law for more than one person to use a gift card,i use them all the time,so does my son,and my girlfriend,and her son,and probably close to everybody else that has ever used one. They then sent me back an email saying that support had approved the card as belonging to me(woohoo),but before i could get too excited they told me that i violated their terms and conditions by using shared financial accounts. As id already explained to them a hundred times previously,a vanilla visa gift card is not registered to any one persons name,and therefore cannot be considered as belonging to just one person,and nowhere in their terms and conditions does it say that…anywhere. I told them that if they had a problem with my method of deposit,they should have told me that $50,000 ago. Instead of reviewing the case.support told me the decision was final and ultimately could not and will not be reversed and that my accounts will remain closed due to a concerning comment i made on chat and my bogus request to be self excluded. I no longer wish to play at jackpot city,but i have done nothing wrong,ive been a loyal and faithful customer who spends alot of money and rarely wins. Isnt that the kind of customer casinos dream of? i feel i have to go to an outside source for another look into this decision because i wouldnt want this to happen to anybody else,this has caused me more problems and stress than anybody should ever have to go through. Especially when ive won before while using these exact methods of deposit and have never had a problem
