Xfinity mobile is denying to to unlock my fully paid off phones

I have been with Xfinity Mobile since 2019, a valued member, as I've been referred to.  Since May 14, 2026 I have been dealing with this carrier locked issue, I have five devices on my plan, 1 smartwatch, 1 iPad, and 3 phones, 2 of the phones were purchased at the same time, in March 2023, the other phone was purchased in April 2023. All five of my devices are paid in full, the smartwatch, iPad, and 1 of the three phones are all carrier unlocked, however, Xfinity is refusing to unlock my last two devices. Clearly I have done some research, I have met my phone installment agreement and the phones are paid in full, I have had service since 2019, clearly thats longer than 60 days and I dont have a plan contract to meet. I do have a past due balance but xfinity should not deny my unlock request based on a past due balance. I have paid over $1,100.00 for each device, my iPhone 15 Pro Max, and my Samsung Galaxy S23 Ultra. These two devices are my personal property they belong to me, Xfinity owns the phone number associated with the device not the device itself. And if a past due balance was legitimate then why are three of the five devices unlocked, one of which is the same phone as one of the locked devices. 

The worst part of this situation is, on May 19, 2026 both of my Samsung Galaxy S23 Ultra phones were unlocked, only the iPhone 15 Pro Max was carrier locked, after calling Xfinity Mobile requesting to have my IPhone unlocked, suddenly 1 of my Samsung Galaxy S23 Ultra phones was locked as well as my iPhone. 

This has been the worst experience, the customer service has been the worst I have ever experienced and for being a valued customer I have been treated as the human on the bottom of a shoe, I can only imagine how I would be treated if I wasn't "Valued".

I have filed a formal complaint/dispute with Xfinity requesting to have my remaining 2 devices unlocked, the 2 most expensive devices on my account at that. I am hoping I dont have to file a complaint with the FCC nor the BBB, however, I have all of my documentation if needed.
