Hi,

I just would like to inquire if it is possible to downgrade the Office 365 that was purchased from a vendor.  The vendor specifically assured us that there would be product keys that would be given and we would be able to use it in on our existing Office 2010 products.  But unfortunately, it does not work.

The vendor is no longer answering our calls, emails text messages, etc after he has received the payment for the Office 365.  

We are located in Riyadh, Saudi Arabia.

Thanks in advance.

Hi,

Who is that vendor? What did they tell you in detail?

In this forum we mainly discuss technical questions about Office products, for the purchase and activation questions, I suggest you contact your local customer service.

You should be able to find your local customer service number from this link:
