I apologize for the confusion. If you're referring to Microsoft Teams, blocking a caller should prevent them from contacting you through Teams as well. However, there may be instances where the blocking feature doesn't work as expected. It's possible that there could be a technical glitch or an issue with the specific configuration of your Teams settings. I suggest reaching out to your organization's IT department to investigate the problem further and get the appropriate assistance to address this issue with blocked calls on Teams.
