What a quality answer! I get very poor quality support from Stripe's live chat, but the professionalism and helpfulness on HN from Stripe people like you and Edwin is beyond reproach, that's for sure.
That is an interesting data point. In my case the support I got from Stripe over the years (email, chat, IRC, ...) has been consistently stellar. Are you in the US?
I'm not in the US. Typically I use live chat during European evening hours, and I often get agents with upper-intermediate English skills, who miss the crux of my question or who are completely unfamiliar with Stripe's own dashboard or services. Not even on an API-level. Simply on a "here's a thing that Stripe has and here's something it can do" level.
