Unwanted Peacock Premium service billed to me, unable to cancel and receive refund

I have been billed for Peacock Premium under the "Other service providers" category on my Xfinity bill for over a year now. I have spoken to Xfinity customer service three times about this, and also reached out to Peacock customer service about this, and I cannot remove the charges from my bill. Both companies say that "due to privacy concerns" they cannot access my account in order to process the cancellation and point me towards the other company for a resolution to this problem. I now believe that these are FRAUDULENT charges and that I have been scammed for years now. I do not use this service, I did not sign up for this service, and I do not want this service. If the billing is taking place through Xfinity, then they have the ability to stop the charges.
