Peacock Premium Plus Activation Error

Last Saturday I placed an order to upgrade from Peacock Premium to Peacock Premium Plus (PPP). When I click the Activate button I get the message "Something unexpected happened". I spent quite a bit of time with chat support before they finally said they would open a ticket with higher-level support for resolution. I haven't heard anything back and periodically try to activate with same results.

Today, the activation link for PPP disappeared and it also didn't appear in my services. I placed the order again, and attempting to activate resulted in the same message. I went to a store to attempt resolution, and they said I would have to call support. Telephone support provided no help, and I was promised a call back from higher-level technical support within the hour. I haven't received a call, and activation still isn't working.

I've attempted activation on multiple devices, networks and browsers, including the Xfinity app.

Can you provide any help or insight?
