Delete Org on Teams Free Version
The following site states you should contact Microsoft Support via Phone to delete the Teams Free org:
However, neither the Commercial Support Team, Office Consumer Team, and Office Business Team know how to do this, based on phone conversations with them. It'd be better if you could do this on some portal or at least gave those teams clear instructions on how to achieve this.
