Huh so many peoples here doesnt know simple tennis rules

Your bet lost as soon as Fils won the first two sets. There is now way how Hurkacz could won with -1.5 by sets, best he could do 3:2.
If your bet had been on a games handicap, they would have voided your bet, as they did with your friends bet since
I think OP knows his bet lost, but since a player has retired, he believe it should be voided and his bet will be return to his balance.
I'm wondering where did you get this rule?
according rules In case of a retirement and walk over of any player all undecided bets are considered void
Because the rules I have layed above, they have references that anyone could verify, so can you please put an attachment of the source?
Duckdices odds provider is shady as hell and I saw lots times how they void winning bets and stays loosing ones. But thats not the case here.
We all know that as we can see on their profile.
