You can't argue when bad faith is involved. Those 4 bets are clearly not the same bet. "who will win the rest of the match" is not the same bet as "full time result".
It is the same if the current result is 0:0.
The casino should not allow identical bets to be placed to begin with, instead of cancelling them after the fact. But you have no case here and you're just digging your hole deeper with dishonest statements. I take it you won 90k+ EUR, which is near the max winning, and that's all you're entitled to.
