Lots of trouble with xfinity assistant chats in trying to get Peacock as a Diamond Rewards member

Problem
I'm trying to get Peacock through the rewards since I'm a Diamond rewards member. When I click on the "Get Peacock Premium at no extra cost" link, it tells me that it's already been claimed and I can go " Go to Activate Peacock. (embed: https://www.xfinity.com/activate-peacock). peacocktv.com to finish setting up your account."

However, when I click on that, it shows me "We’re sorry, your account isn’t eligible for this Peacock offer". 

What I've tried
I reached out to xfinity assistant chat twice. 

• The first chat, they told me that they see that I've claimed it in 2023 but have not created an account (which I had, but that's ok). They said they'd help create an account for me and I would receive an email 20-30 minutes later to log in. I was ecstatic that the problem was resolved so quickly - gave them an excellent review through the survey. I waited 20-30 minutes, but no email. I thought that maybe it'd take some time, so I waited another couple of days but still no email. So I started another chat.
  
  
• This second chat was much more frustrating, it spanned about 2.5 hours and I got switched to 3 different agents. 
  1) The first agent told me that I had claimed the offer in 2023 and as a result, since the 2023 offer is no longer available, I cannot claim the offer again. So I asked if they could reset that, because, why would that negate me from getting Peacock now? They had no response and offered me a Xumo box, which I already have. I told them no, I don't want it. Then they said that my current account is missing my Xumo box number, so they needed me to accept the agreement through text. I repeatedly said no again, because I did not want to be sent another Xumo box, my current one was working just fine. They insisted that I accept the agreement through text because my Xumo box needed to be assigned and that I would not get another one. So I accepted. Lo and behold, I received another Xumo box today. What do I do with that? Can I just return it? 
  2) After that, I suddenly got switched to another agent and I had to start over. This agent also ran me through the same thing, click through the rewards link and the activate Peacock link. Same issues. Then they said, well, you can upgrade your internet to 1 gig and that will get you Peacock for free too. I said no, I don't need 1 gig and why would I if I should be getting Peacock free through my Diamond rewards?
  3) Somewhere in there, I got switched yet again to someone else. Started the whole process/explanation of my issue over. Finally they said that they could file a ticket with the Rewards team that should be able help. A ticket was created and I signed off, hoping that the rewards team would be able to help. In all, this second chat lasted about 2.5 hours, with no resolution and an extra Xumo box that I don't know what to do with. 

I got a response from the Rewards team ticket today - they suggested the exact same things, click on https://www.xfinity.com/activate-peacock to activate. Which as I've had to repeatedly note, leads me to "We’re sorry, your account isn’t eligible for this Peacock offer". 

Where I stand now

Can someone please help me? I still don't have Peacock and now I have an extra Xumo box. This has been an incredibly frustrating experience. Thanks for reading.
