I've recently relapsed, which I'm ashamed about, but it doesn't help when these overseas and unlicensed casinos don't let you withdraw your money.
I was playing at a casino where I deposited £1k but it automatically (I didn't ask for it) added a bonus of another £1k. They then told me I needed to wager 40 times the bonus to get my money back and that only 10% of blackjack (which is all I ever paid) goes towards the wagering. Basically this means I'd have to gamble £400k to unlock the £1k bonus they gave me. Actually worse, because I can't get my original £1k back without wagering.
I asked them to cancel the bonus and they "generously" allowed the wagering to be 3x my original deposit. But they kept the 10% from blackjack. Meaning I'd have to gamble £30k to get my £1k, which is not part of the T&C incidentally.
I gambled these on a credit card with Mastercard. I am obviously going to do a chargeback. What should I put it through as to be most successful and what do I send as evidence to support it?
