1xBet Paid Me Less Than My Winnings From Flamengo Bet

I bet $100 on the Flamengo - Bayern match in the 1xbet app. Bayern won, but my bet only brought $85 instead of $115. My account is 1904728***. I wrote a request to 1xBet support service, but my requests remained unanswered. Help me figure this out, this has never happened before? How is it even possible to win with a negative coefficient less than the bet amount? Fix it immediately!
