inexcusably

Without valid justification

Inexcusably describes doing something in a way that cannot be justified or forgiven: The report was inexcusably late.

It emphasizes that no reasonable explanation exists for the failure or wrongdoing: He was inexcusably rude to the staff.

The word carries strong moral judgment—whatever happened, it shouldn't have.
