Betmarlo Online Platform Takes Back Winnings, Restricts Access

I've been playing games on Betmarlo.com for a while now without any issues until today. It seems some sites are quick to impose restrictions on lucky winners. When you lose, there's no problem, but when you win, suddenly there's a risk involved. Tonight, I deposited ₺5000 to bet on an NBA basketball game. My bet won, so I requested a withdrawal in the morning, only to have it canceled. When I contacted live support, they claimed there was a "platform update" (the usual excuses) and asked me to try again after 14:00. However, when I checked the site around 13:00, I saw that my winnings were canceled at 11:27, and my main balance was restored. When I spoke to live support, they informed me that their dear risk management team had decided to cancel my winnings and restrict my access to sports games, allowing me to play only in the casino section. This implies that winning in the casino section is impossible, as they admit zero risk on their end. I managed to withdraw my main balance just now, thankfully, but I won't give up on my winnings. I'm declaring here that I won't be playing games on this risky site again. I've also lodged a complaint with their licensing authority, and I'm confident I'll receive a positive response.
