I'm really sorry to hear about your gambling addiction, addiction is not fun for anyone and I hope you get help with your addiction.
If I was you I should focus less on getting my money back and be happy that they are ready to refund your deposits from the third account.
Then you should try to get help with your gambling addiction and really try to quit once for all so problems like this not occurs in the future.
You can do so much more and funnier things for your money rather than throw it away in gambling, trust me.
Good luck.
You tried to explain it well but it is very difficult to bring back those who get addicted to casinos. I have also seen those who could not come back and were ruined. If I were in his place, I would have done the same things as you because if I tried to get more, I would have lost everything, so I would have tried to come back from here.
However, what I see is that if casino players spend two days making good profits and then lose a lot of money, these are the most observed things now. I think it would be best for him if he could get out of here.
