Uhh, to be sure we're on the same page, I understand by "batter" you're referring to "bettor", thus, the player? If you are, then: yes.
To clarify, the multi-bets were cancelled by the casino and there were no winnings as the event [that should be won by the player suppose the casino did not cancel it by themselves] "were not finished".
We are on the same page, I meant "bettor"
When a bet is cancelled [void] then the stakes should be returned. Has he got the stakes returned?
Yes, according to both the OP and the contact I am in touch with,
What happened: Betfury has cancelled open bets that would win ~$400k. They have refunded the value of the initial bets which was ~$100k. [...]
Betfury has only refunded the initial bets which amounted to just over $100k.[...]
[...] If any of those unsettled selections of the OPs betslips were wrong selection and for the same reason [whatever it was] if the bookmaker would return his stake [making the slip void] then we would not see this topic in the first place. Do you agree with this?
Uhh... I'll have to say no, for the fact that the case exist despite the stakes being returned. The problem we're trying to solve here is not the bets voided alongside with the stakes. The stakes were returned. There's no problem in that.
It was the multi-bets got cancelled by the casino, where --far as I know [and by that I mean I've raked their ToS]-- there is no clause that justify them to cancel bets from their side. If a match got cancelled because of a a riot happened, or a blizzard, or the moon suddenly decided to land on us, or Ronald Weasley cast that slug-vomitting spell on the players, then yes, I think the multi-bets will rightfully be cancelled. The match didn't meet its end.
The problem with OP here was: all of his multi-bet reached their end. He should have won, suppose the bets were not cancelled by the casino.
Uhh... OP,
dplay, help me understand, walk me through your shoes and help me see through your eyes, how did you place your bets? Why do you think, in your wildest imagination [and please be fair on this], that the casino considered your betting preference as something worth flagged?
I am not accusing you, nor trying to find a way to invalidate your dispute [in case that idea ever crossed anyone's mind], I am trying to understand your situation immersively, so I can be "you" and see if the casino's call is justified and/or what to say as rebuttal.
