Very often the responsibility lies with the buyer, never with the seller. In the specific case of purchasing Genshin Impact virtual currency, each seller uses the disclaimer that the method is “not 100% safe”, but in reality it is because the seller requests the refund after topping up your account.I was fooled by the very low prices I found on z2u, but they are a scam. You are told you might get caught, but you don’t get caught, it’s just the salesman who gets you in trouble.I bought from another site recently and nothing like this happened with this site, never buy Genshin Impact virtual currency on Z2U, go to others.
