Unable to Upgrade to Peacock Premium Plus (StreamSaver)

Hello — I’m requesting assistance and escalation with an ongoing issue upgrading my Peacock subscription.

I currently have the Xfinity StreamSaver bundle and am satisfied with my plan overall. However, I have been trying to upgrade from Peacock Premium to Peacock Premium Plus, and the upgrade option is not working.

When I attempt to upgrade through the Xfinity app, I receive the message:
“We’re unable to complete your request.”

I previously contacted Xfinity support in February and was told the upgrade must be completed through the app. I was also told a request was submitted for Peacock support to follow up, but I have not received any contact or resolution since then.

At this point, I am requesting escalation and resolution. Please:

1. Confirm whether Xfinity or Peacock must process the upgrade, and  
2. Complete the upgrade to Peacock Premium Plus on my account.

Thank you for your help.
