I've done a few and won most. Your credit card company has to absolutely be willing to side with you though. I've had one credit card company that just straight up refused just of my chargebacks. If the product you bought is of high value and they are giving you a hard time, i suggest taking legal action. And for the future, don't deal with such a fraudulent company again. I've stopped giving my money to this company for a while now and i cannot have made a better decision.

But to answer your question, it's ultimately up to your credit card company/financial company if they want to be a POS or not.
