Streaming Netflix thru Xfinity cable box

I have Netflix included in my Xfinity cable package but I am not able to sign into Netflix. 

On screen Netflix says I have an account but again I cant sign in.

I have spoken to Xfinity technical support 12 different times since August 21, 2023

I have spoken to Netflix independently as well as twice on a conference call with Xfinity

The problem has been escalated to the advanced team at Xfinity and they escalated it further to the Tier 2 team and then to the Tier 3 team

I spoke with Dan [Edited: "Personal Information"] from the Wilmington, Delaware office who said he would oversee this and call me back which he has never done. But he told me to call get transferred to Advance team and ask to be transferred to him which doesnt work as I'm told they cant do that.

I have probably had 7 different ticket #'s and any time I call back they have expired.

Netflix has told Xfinity that for some reason the sign in screen I am getting is an old screen and it needs to be updated.

I have had more refresh signals sent than I can count, I have had my cable box replaced twice, I have the wiring in my house redone twice, I have had people working on the outside wiring on the poles.

The fix I am told by both Netflix and the Tier 2 & Tier 3 people is in Xfinity's computer system and yet I cant get this done and if I call back I get the first level technology people who all think they can help me and they waste over an hour of my time and theirs doing the same things that have been done a dozen times already because they either wont cant transfer me without first trying to fix the problem on their own.

So how do I escalate this to someone who can help oversee that the work will be done by the tier 3 department or by whoever needs to fix this?
