Hey there!
Nice to meet you! I'm Darhyl, an Independent Advisor.
Based on your description, the Robux on the Microsoft Xbox Store is only for the Xbox console platform.
You will have to purchase Robux on their official website if you are playing Roblox on PC:
https://www.roblox.com/upgrades/robux
Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
Since you purchased the in-game currency for the console, I highly recommend requesting a refund by signing in to your account and follow the instructions through the Xbox Refund Webform:

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.
Best regards,
Darhyl
