Apple Watch Series 12 activation -- Tech Spot resolution date missed

I am requesting escalation of an unresolved Xfinity Mobile Apple Watch activation issue. My Apple Watch Series 12 GPS + Cellular is being rejected by Xfinity as “Watch not compatible.” This has already gone through advanced support and backend escalation under ECM0025392330 and Tech Spot ticket CAS4238059. I was given September 22 as the resolution date and instructed not to retry activation until then. It is now September 23, I retried activation, and the exact same incompatibility error remains.
I have already spent several hours with Xfinity Mobile support and do not want to restart basic troubleshooting. I am requesting review by Executive Customer Relations/Executive Resolutions and confirmation of what happened with the existing Tech Spot ticket.
