15 please

In fact another player retired match and automaticly lost game. Why sportsbook not give my winnings? In fact retired player lost match.
When sportsbook see if this player win game they lost a lot of money and then they call players manager and tell them now retire match or we lost more money.
Is this possible?

And you know I am right

I wrote them just waiting answer. 

I want to explain that if Player retired it mean he automaticly lost game, and another player winner.  If player retired before match start yes then match will be void.
And I bet winner player.

So when bookmaker see if this player will win match we will lost a lot of money. Then end of the mach last game he call that player and tell him ok retire the match or we will lost a lot of money. And player retired match they refund moneys. It is not justice

I wrote their livechat, but they said bet voided. I want to understand until voided my ticket won game +4.5 why my ticket should void? If game voided why under 18.5 tickets lost?

Just I show my betting slip photos to you. I make Tennis Player win game +4.5. My please lost first set 3-6, 2nd set won 7-6 and 3rd set when my player won game 5-0 another player retired game. How ever my player won game +4.5, But Sportsbet voided my bet. How it possible? How ever my player won game. It this justice?
But more people make bet the same game under 18.5 they lost their money, If game voided why their money also didn't refund back?
Explain me please
