Please answer the following questions to assist you properly :

PS: Don't share your email or the controller serial number. Here in the forums no one can access / modify account details or similar due to privacy and security reasons

As far as I know the warranty for a replacement is 90 days.
But you can double check that with Microsoft

You can update your warranty if the date displayed doesn’t match with the one from your receipt.
