I'm really sorry to be the bearer of bad news, but this casino has had scam accusations and I haven't seen any cases having a happy ending in which the person who is accusing got what they wanted, that's why my advice to you: take your 1000$ and withdraw from that casino, you will not be able to get what you are complaining about, simply withdraw your 1000$ and forget about it, you can see this case:

in this case, they unlocked the account of the guy who was complaining because he didn't win anything, I assume that's it, but in your case, as you've already seen that you have a balance of 1000$ which is what you deposited, it means that they won't worry about it anymore solve your case because they already refunded what you deposited and did not consider your winnings, it is useless for you to continue complaining, you better withdraw the 1000$ and forget about this matter and not use this casino anymore
