Your first post literally says gambling. If they aren't yet accepted then that's the reason why. Revolut is mastercard. Mastercard doesnt allow chargebacks where gambling is involved. It's not an argument. I'm just saying how it is so others don't make the same mistake. Im not sure why you have your back turned up so much, its very peculiar. I will stick by what i said to help others out. If you don't put in the effort and read what's available on here, and still fail with a chargeback - then I have no sympathy for you.
