The game not played as predicted, but it started with disadvantage from me against casino, when they accepted an outdated odd.
I placed dozens of bets and I know it was wrong. Their support continue saying that if I had another option selected the bet would be placed with 2.15 odd:

Judging from the conversation between you and the casino representative as given above, it clearly shows that the bet was accepted with the new odd of 2.15, of which I'm sure if only had the game played as predicted, what O.P would have won is $2150 and not $1500, but since he/she lost the bet, he has technically also lost his betting amount (i.e $1000).
OP's issue here, unless I understand it wrongly, is that since the odds changed, his bets should not be accepted in the first place, and thus, voided.
But why will such issued be raised after he (O.P) has lost his bet, where was he long before the game played to either cancel his bet or cash-out his fund since he wasn't okay with the changed of odds..I think this is already late, as this is a common issue we gamblers face every blessed day
WHY MUST IT BE NOW AFTER HE HAS LOST HIS BET TO COMPLAIN OF NOT BEEN OKAY WITH THE CHANGE OF ODDS?
