Never, and getting that chargeback right before the commission should be paid also smells like a scam. I would ask for detailed proof and I’m unsure how the hell can someone charge 20k back just like that. The casino should be onto this matter as well and I don’t think there’s nothing they can do. I’m saying this especially because CasinoLasVegas is a part of bWin.Party, if I’m not terribly mistaken and they are a publicly listed company, instead of some RTG powered illegal company.
It really seems like something sketchy is going on here. I’d expect them to pursue legal action against the person who made a chargeback too.
You should likely have a good chat with your manager about the whole situation, as ”yeah, there’s a $20k chargeback, sorry bro” wouldn’t cut it for me. I imagine they can’t comment on a private situation in public, but keep us updated in this thread.
