Because HN is not your support forum.
An unhappy Stripe user has zero obligation to do any damn thing you prefer for the sake of helping you with your PR. They were counting on you for a vital service and you failed to continue providing it through a very abrupt termination of that service with no further internal recourse available. Despite this they should keep their complaints private unless they detail them in just the way you'd prefer, where you prefer? Fuck outta here...
Stripe already has a burgeoning track record of shitty behavior to users from what many of us have seen reported here and elsewhere, but this smugness from one of its own staff on a third party site is a nice bonus.
I will reiterate that we'd like to grow with any user we have (particularly a long-tenured one!). However, we can't support businesses with excessively high chargeback rates, no matter what. Keeping chargebacks at an acceptable level is a financial obligation for every business: https://stripe.com/docs/disputes/monitoring-programs.
So, we make it as easy as possible to submit evidence. The cardholder's bank decides whether the chargeback is won in favor of the business or not. The card networks are aware that "friendly fraud" is increasing too, hence the introduction of Compelling Evidence 3.0 (more to come on this): https://support.stripe.com/questions/how-does-stripe-support....
Is there a way in the stripe dashboard to see my chargeback rate? I think I’m closer to .1% than the .75% you said is a problem, but hard to know 100% how you are calculating it on recurring revenue.
With a SaaS, maybe try a trial period and monitor is the customer actively uses the service, and make sure you notify them before you start charging. Often I signup for a trial, find out the service is useless but forget to cancel. That first charge is a prime cb candidate.
