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?
Don't gamble.
If you really have to break that rule, risk only what you want to lose.
If the money was really important to you, why did you deposit it into Primedice? I know you just wanted to make a little profit, but did you really think?
Learn from your mistakes, get over it and move on.
