I also have removed my support for the flag, judging by your response which you deleted it seems pretty clear to me that your excuse is that you share a wallet with your partner.
Whether or not that is true, you should see sportsbet.io’s side of this and agree that you have got your deposit back and learn from this to not share a wallet with a partner who has another account as the evidence linking you will be very clear.
Luckily for you it was not an extremely expensive lesson.
