We are sorry to hear this has happened to you, however, we are not in a position to refund any bets you made by mistake.
As you understand yourself, it is impossible to check if that was your intention or not.
It is only a player who can place bets, neither a system nor we can do that. So it is solely your responsibility to control this.
Please consider making sure your device is working properly or setting limits in your account in order to avoid situations like this.
