I'm also not sure if the person/bot who responded was saying "No refund" or that they couldn't issue a refund, or if a Github Issue was an appropriate place to ask for a refund.
Let's hope a human on the other end is reading this and acting accordingly. It all seems like we're only seeing part of a story.
Given that, it's almost guaranteed that sasha-id is a legitimate actor.
If you're confused about sasha-id's comment here (https://github.com/anthropics/claude-code/issues/53262#issue...), it's because they just copied and pasted a support response from Anthropic.
In this particular case I think the authors reply is them quoting what support told them?
It was obvious to me, but I can see how somebody could get confused from that.
