Hi Ae soft,
Welcome to Microsoft Q&A! And sorry for the late reply.
I understand how frustrating this situation is, having warranty orders repeatedly canceled without clear explanations, and being redirected between support teams. I’m sorry you have to deal with this, but before getting further, I need to clarify something:
Microsoft Q&A is a user-to-user support forum, limited to providing guidance on technical issues. Moderators, contributors, including external Microsoft staff, do not have access to the internal processes, and cannot intervene with Support workflows.
The cancellation is often not random, but unfortunately frontline support often also doesn’t see the internal reason themselves. In case you needed, I can give some common causes that could be the reason for the cancellation that you can check out:
- Device flagged for serial number history mismatch, regional mismatch, or prior replacement history.
- Duplicate or overlapping warranty replacement attempts detected by the system.
- The device associated with a different Microsoft tenant (consumer vs commercial/education)
- Account-level blocking due to repeated replacement attempts.
- Warranty eligibility technically valid, but blocked due to compliance or fraud‑prevention review.
My suggestion forward is that instead of reopening another warranty cases (which will likely get canceled again), you can try to contact Microsoft Support and ask them to explicitly explain the reasons for your cancellation.
I know this isn’t the transparency you were hoping for, but hopefully this gives you a clearer path, so you don’t get stuck in the same loop again. Sorry for not being able to help further than this.
