peacock problems

I need help to cancel a Peacock account. I've been dealing with Xfinity's so-called "customer service" for the past 4 months to no avail. The problem is as follows...

Several months ago I cancelled TV service, returned my X1 box and upgraded to 1 GB internet service (which includes Peacock Premium which I am now using). My bill reflects a $0.00 charge (which is correct for the Peacock Premium I am now using)-- but also has a separate line for "other services" which keeps billing $2.99/month for another Peacock. I have called "support" at least 3 times. Each time it took me over an hour of dealing with bots and chats before getting to a "live" call center person. Each time they gave me a $2.99 credit and said they resolved the problem. But they didn't. My most recent bill shows another $2.99 charge for Peacock. Today I went to an Xfinity store and the manager was awful and incompetent. Needless to say ,,,,I still need help.  Could someone from Xfinity please help me resolve this!!!  The relations between Xfinity and Peacock is truly a loop.   The Xfinity store manager told me he could do nothing  and go to Peacock. The Peacock website clearly says go to your 3rd part provider (Xfinity) if Peacock is billed through them ( which this $2.99 charge clearly is). I am so frustrated with Xfinity -- therefore I am having to type this. PLEASE HELP ME!!!! The $2.99 charge may have been attributable to a "trial" Peacock which I got when I had my X1 TV box (which I no longer have). I believed I terminated this trial, but the Peacock still exists and so does the $2.99 charge. Peacock will have nothing to do with it because it is being billed by Comcast. Comcast Xfinity so far will have nothing to do with resolving this (based on all the contacts I've had thus far). Will someone from Xfinity please come forward and resolve this? PLEASE HELP ME!!!!
