If you know the risk at first on playing gambling then you should didnt risk that money.It does really hurt and im feel sorry on your losses man and expect that admin or staffs of PD wont reply on your emails since there is no refund once you lose the money.If you lose it then its your responsibility.
I know It's my fault, I lost my everything, what I do now?
there's nothing mate unless you can accept the fact and move on, stay away with gambling there's still life after this mistake if you are really willing you will be able to find some ways to overcome this i know its hard for the owner to give you back your loses and that for sure because if he will do that most of their gamblers will do the same.
