Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
https://support.microsoft.com/contactus/ getting support over here is a super rocket science, options not showing. Not sure, if it due to my windows version is out of support.
To answer the queries-
- I have valid proof (invoice) of the purchase.
- The validity of the license was lifetime
- I can't remember the way, it was delivered. Probably both, over display on device and hard copy. However, none of them is recoverable.
- The machine where it was installed was suddenly ripped off the licenses and asking for it whenever opened. So, yes, the license was successfully redeemed on my machine after the purchase.
