Yeah, I know chargebacks are a frequent vector for abuse and of course I don't mean to imply that customers doing chargebacks ought to always implicitly be given the benefit of the doubt.

Given that you are responsive to inquiries, it makes sense that you'd rarely if ever have a legitimate chargeback -- because there's no reason for a customer to resort to chargebacks if the vendor is willing to work with them to resolve legitimate issues.

But I know of many examples of people needing to resort to chargebacks due to ineffectual customer support, and then having their accounts banned and being cut off from other unrelated services from the same vendor as a result. I don't think that's an appropriate response and vendors should be careful not to let that happen if they instate such a policy.
