My card issuer just gives me a credit when I want to chargeback. They're like, oh you don't want to deal with a real chargeback, just have your money back for free. I would've pressed it since I kinda wanted the company to regret ripping me off, but I already got my money back so it wasn't worth the extra effort.
That's how chargebacks often work. Then they ask the merchant for evidence the charge was legitimate. If convinced, they will retract that initial quick refund.
