Hello Josh,
Thank you for reaching out to the Microsoft Community. I'm glad to assist you today.
Have you tried adding a different phone number from another carrier to see if you can receive the verification code? Sometimes, certain carriers may experience network issues, or there could be a problem with your specific number. Changing it might help you receive the verification code and claim your rewards.
If you're still experiencing issues, please try resetting your Microsoft account password. Choose the phone number option to verify your identity and check if the verification code is being sent. Alternatively, consider adding a new verification method (another phone number) to see if you can receive the verification code there.
