Hi Travis,
In this situation, the only reliable way to get replacement product keys is directly through Microsoft’s official support channels. If the install team didn’t provide them, you’ll need to request reissue from Microsoft by opening a support case tied to your licensing agreement. The fastest route is to contact Microsoft Volume Licensing Service Center (VLSC) or your licensing reseller, since product keys are distributed through those portals. If you’re being disconnected by phone, try submitting a case online through the VLSC portal or escalate via your Microsoft account representative. Avoid third‑party sources, only Microsoft or your licensed reseller can legally reissue valid keys.
You can start by reaching out through the Microsoft Volume Licensing Service Center, checking your reseller account, or opening a support case.
Harry.
