Unable to activate Netflix, technical issue needing Xfinity side support

I purchased a streaming package two weeks ago that includes Netflix. I have been able to activate and sign in to each streaming account (except Netflix) using the links provided by Xfinity. When I try to activate Netflix, I get the same error message that "this task can not be completed at this time". I have called Netflix several times and verified that I do not have a previous or newly registered account with Netflix. They said that this issue would need to be fixed on the Xfinity side. I have been through several frustrating weeks of trying to contact Xfinity via the phone or with the message bot. Neither robot seems to know how to handle this. I finally got through to a person and they told me this issue requires higher technical help and that I would be getting a call from their tech team within the hour. It has been 6 days. PLEASE help me fix this. I should not be paying for a subscription that I can not access. I should not have to fight this hard to get in contact with someone (a real person) to help me out.
