I cancelled via chat 2 weeks ago. Was just asked 1 question by the bot which then forwarded the transcript to a live agent who then went ahead and cancelled without further questions. Maybe they updated their policy recently?
Fwiw I think slack absolutely nails this and is a net positive for them in the long run. They automatically refund inactive users which means you don't need to "think" too much about adding people. I wish more companies would experiment with this kind of "honest" billing vs expending all their effort on layer upon layer of dark patterns.
This is almost like that. The WSJ is bad too. But I’ve noticed that cancelling and restarting my Audible sub was totally painless.
