There are OEM and retail versions of Windows and the key for one will not work with the other. I seriously doubt that any site that sells keys would give a refund for any reason.

Are you trying to activate online and it's just failing, or is it saying the product key is invalid?

If it's saying "Invalid" then you installed the wrong version of Windows (OEM vs Retail) - if it just won't activate, then you need to call it in.
