No doubt all the rogues are gonna take advantage of this dilemma. They'll make a way to get your money to them, but it's a one-way street. Money wont come back your way.
Wonder why payouts cannot be returned to a credit card charged as a merchandise transaction.......if I use a credit card at a department store, then return the purchase to the store, my credit card is refunded.
If they're actually claiming that they're a casino to the CC company, they're not allowed. If they're using shady means to push the charge through, then they should be able to treat it as a "return".
Personally, I wouldn't touch a casino that was doing it via the latter method with a 50' pole.
So you'd miss out on those big juicy bonuses?
Credit cards give you much better protection than Neteller or other webwallets.
