Payment details refusing to save

Question

I purchased a product key from Harvey Norman for Office 365 but when I enter the key it refuses to save after entering the payment details and just after the are you a robot test

Answer 1

Could you please clarify what happens immediately after completing the verification? Does the page remain unchanged, does the Save button become unresponsive, does it return you to the payment information screen, or do you receive a specific error message? Also, are you redeeming your product key through https://microsoft365.com/setup, or through a different website? Could you confirm whether the product key was accepted successfully before you reached the payment screen? If possible, please share a screenshot of the page where the process stops, hiding your personal and payment information.

As an initial suggestion, please visit https://account.microsoft.com/services and check whether your Microsoft 365 subscription is already listed, since the product key may have been associated with your Microsoft account even if the final setup page did not complete.
