I have 3 succesfully chargebacks.
2 through Revolut and one directly from merchant.
as somesone mentioned earlier, a55.tech refund direct without question. Also cardflare.io made a refund direct.
Kryptomin refused at first, but after I requested the MCC and told it was made via a casino, they accepted my request of refund.
I refer to their ToS, as it often says i-gaming etc is forbidden to use from their side.
