Xfinity Mobile won't unlock the phone after fully paid off after talking to multiple "customer support"

I am writing to request an unlock for my phone. I met all eligibility requirements for unlocking, e.g., 60 days passed, paid off phone]. An agent previously told me it would be unlocked within one hour, but it has not happened. According to Xfinity's policy, it should unlock automatically within 48 hours. I would like assistance with manually processing this unlock.
