How do I still have Peacock Premium and am I paying for it?

Hi there. I am no longer an Xfinity/Comcast customer and have not been for months. I have not been billed directly by Comcast for anything since early July. At the time I used to be an Xfinity internet subscriber only (no TV or phone or anything else). As part of a promotion, I guess?, I got Peacock Premium. This was years ago when I signed up.

Checking today, I still have Peacock Premium. And while this may seem cool and great like I'm getting a free streaming service, I'm worried that I'm paying for it somewhere and just haven't figured out where yet. 

Steps I've tried:

1. When I log into Peacock I get this message on my accounts page:

"Peacock Premium:

To make changes to your plan or cancel your subscription, please visit the Xfinity subscription manager on your Xfinity device."

Well I don't have an Xfinity device. In fact I never have. I always had my own modem and never had a streaming box.

2. So then I clicked the "Manage on Xfinity" link in Peacock

3. Logged into Xfinity (even though I do not have any active subscriptions with them)

4. Clicked on "TV & Streaming"

5. Here I am presented with a few options related to Peacock.

Streaming > Peacock Premium (with a button that says "Add & manager on Xfinity StreamStore")

Premiums > Peacock Premium (with a button that says "Manage premium channels")

Equipment > No Devices (with a button that says "Manage Streaming Equipment")

6. Selecting "Add & manager on Xfinity StreamStore" takes me to an error page that just says "We're sorry. Please contact us and one of our friendly and knowledgeable representatives can help."

7. Selecting "Manage premium channels" takes me to the same error page.

8. I have tried repeating these steps in the mobile app and see "Peacock: This information is unavailable at the moment" in the "StreamStore Subscriptions" page.

I'd really like to figure out how to manage my account, see when my trial expires, and stop it from charging me if it is doing so. I've read other things on Reddit where Xfinity says your trial should just stop when it expires, but my trial should have expired long ago given that I no longer have a contract or service with Xfinity.

Please do not provide a canned solution here. Please read through the steps I've already taken and offer me novel advice.
