He’s not wrong. The length of the reply doesn’t make it good or worthy when most of it is wishy washy we’ll do better in the future we promise without any concrete steps to make that happen or metrics to prove so. In fact I would say he’s doing a bad job by the amount of stripe fucked me posts here recently.
You don't hear about the positive outcomes of support cases, but you'll hear a lot about those that don't work out the way they're supposed to, and you'll also hear a lot about those where someone feels wronged even though they've misbehaved.
The complainer can also misrepresent the case, while Stripe cannot disclose how they see it. Making any assumptions about service quality on that base is not wise.
