This isn't true. Visa/Mastercard care about your chargeback rate. You can block a customer who's done a chargeback. I'm sure the card networks have rules around what you cannot do as a result of a chargeback but you can stop providing services to a customer who has done a chargeback.

Disclosure: I engineered and delivered a high risk payment processing gateway to a firm specializing in being a cc processor of last resort, also working with merchant banks of last resort.

To be clear, my views on this are not legal counsel, they are simply from having worked in this area for a decade before becoming CTO at a global bank.
