admitted the facts but refuses to pay

I am filing a formal complaint against Betmatch for a wrongful settlement of Bet ID: 163.
I bet on the interval 16:00 - 19:59 (Portugal vs Uzbekistan) for a Goal to happen first. A goal was scored in the 17th minute. Betmatch settled it as lost, claiming a "foul" happened first.When I challenged them, Betmatch Support sent me the following official explan­ati­on:­"Ac­cording to the match protocol, the foul occurred earlier, and the game was officially resumed from this set piece, after which a goal was scored."By their own admission, Betmatch explicitly states that the foul occurred earlier (which was in the 14th minute, completely outside the 16-20 min interval). The resumption of play from a free-kick is not a new foul. Therefore, the very first event that occurred inside the 16-20 minute interval was the goal .Betmatch is using a ridiculous logic to steal my winnings, claiming that executing a prior free-kick counts as a "foul" in the current interval. Since they admitted in writing that the foul was earlier, my bet is factually a winner.
I demand my full cash payout which is 21000 Ft.
