Diamond Customer - Unresolved Xfinity Stream Issue and Support Complaint

I am a Diamond-level Xfinity customer requesting assistance from an Xfinity employee and escalation to technical support.

My new Samsung TV cannot load Xfinity Stream content. I have received errors SDI 0001, TVAPP-0001, TVAPP-00500, and TVAPP-00611.

I spent 1.5 hours troubleshooting, followed by another hour with an Xfinity chat representative who repeated the same steps and then stopped responding without resolving the issue.

I have already restarted the TV, updated the software, reinstalled the app, reconnected Wi-Fi, and signed out and reactivated the app.

We recently transferred our Xfinity service to a new address. Please investigate account provisioning and streaming authorization associated with my previous and current service addresses.

I am requesting a formal escalation, review of my unsuccessful support interaction, and an opportunity to submit my complete complaint privately.

Please have an Xfinity representative respond and invite me to direct message the support team.
