Moved and lost my reward diamond status

I've been a customer for over 30 years.   When I go to the website to join, they say I'm not qualified to get rewards.  I’ve talked to several  Xfinity support reps, many of whom tried to sell me a mobile plan.  They've submitted 5 tickets to rewards support on my behalf. I received an email verification about each ticket  from rewards support but also at text 1  minute later saying ticket is closed. .  I finally connected with 13 persons who has worked with me.  She said the reason that I can get on the rewards is because my move restarted my service time from 23 years to 0. I only moved and did what I was told by each rep. I never changed my primary user email. The account number has changed but I was not allowed to transfer from Washington to Tennessee because the agent said it was different system when I returned my DVR box Aug 8 before the move and paid the bill before autp pay cold take I in case of a banking issue. .  This makes absolutely no sense.  This is unfair and it’s simple to fix the code to allow for a 30+ years loyal customer to get back my Peacock Premium rewards I have enjoyed for over 2 years. . The Rewards Support does not and cannot communicate with the customer directly.  This is extremely poor customer service. I wrote the CEO but doubt he will  get involved. Big business can loose 1 customer I guess. I spent 22 hours the last 8 days with 13+ agents and each make it worse. I cannot even get my past bills for this year from my ole address uless I go visit a store 2 hours away they told me and also nothing they can do. Called the Veterans department and they said my husband OK and registered at both addresses, WA and now with moving in TN. I have no eligible account now to upgrade. I am determined to get this fixed so I get my account rewards back. Fronteir keeps calling on all us to leave Xfinty and let us try Fronteir. I just may have to. One agent told me to just buy if I want it, That is not the point. I had it for years and now I want my reward status back or at least to register so then the Veteran upgrade can take place. No way to treat a Veteran.
