Subscription chargebacks cluster in two reason codes that are nearly always refund-path failures, and neither pure automation nor pure letters wins them alone.
Subscription chargebacks cluster in two reason codes: 13.2 (cancelled recurring) and 10.4 (other fraud, card-absent). Both look on the surface like billing problems. They are nearly always refund-path problems. The customer wanted to cancel and could not find the page; the customer cancelled and the system kept charging; the free trial converted before they noticed. The dispute is filed because the chargeback is the easier route home than the merchant's refund process.
The evidence is partly technical (login records, cancellation events, dunning attempts, the actual screenshot of what the cancellation page showed on the day the customer visited it) and partly contextual: the merchant has to read those records and reframe the case in a way the issuer's analyst can use. The dispute services on the market split along this line. Fully-automated platforms can pull the technical signal at scale but cannot reframe the case; they submit the data and lose on framing. Templated-letter services do the opposite, writing a coherent argument with no depth to the supporting data, and lose on substance.
Subscription disputes are the cleanest demonstration of why neither approach works alone. The case needs both halves done at once (the technical record retrieved, the human reading of what it actually shows, the letter written for the specific reason code and the specific issuing bank), and a hybrid structure is the only one that delivers both.
