A postmortem — software bug fix please.
1. Why did this happen?
2. What was the root cause in billing that caused this?
3. What are you doing to fix the issue that will ensure that if this error was to happen it escalated to the right medium expediently? What is the SLA on disputes?
One would like to know why were https://slack.com/help/articles/204368833-Apply-for-the-Slac... changes not applied to billing this time around?
With great power comes great responsibility.
