I am sure that being forced to spend time on this steals time from more interesting projects.
I'm not defending Slack here, but allowing this to hit the wall and then raising a stink online does everyone a disservice.
Edit: by "you", I mean "the organisation of Skyfall". It's already pretty clear from the number of people chiming in on behalf of the company that this problem has been handed out piecemeal.
How long have they had the bill mentioned in the top comment on this post? At the very least it's 3 weeks, and the comment suggests it is months.
Both times I’ve paid the new price for 1 year and cancelled. Both times our sales rep was surprised the next year when we didn’t renew.
I'm not denying that what you describe happens, but in this case - ignoring the warning signs, letting the issue crash into a wall and then complaining online about it doesn't help anyone.
