... what matters is your customer's card-issuing bank's chargeback policy

That's what the banks want you to believe. Actually what the card issuer say matters very little except they can withdraw your money.

There are plenty of ways of collecting unpaid debts is what card issuers don't want merchants to know. A cardholder must be very unhappy when they realize they are not legally protected by the bank. Losing a chargeback does not forfeit your rights.
