Hd update issue

AT 7 pm prime time tv on 11/30/22  suddenly narrative box appears on my HD screen blocking view. Instructions to "update HD" as says  no longer allowed HD. Give link to web site to do so. Another box appears saying "View SD" Neither link is valid or usable. Spoke w/lady in foreign country who reported she had done steps need to restore HD that I unable to do. Even had me listen to new Terms & Conditions. I declined option for auto pay and paperless billing. The monthly premium suprisingly was reduced.  Did not work; did not change my home screen; no HD. Next day, Friday, another phone call, to lady named Heaven Tech support who transferred me to a different Rep who set up appt for tech to come to home to resolve. Appt was next day, 10 am Saturday Dec. 3. No show. Contacted Chat guy who reported no record of any appt.  (I copied and pasted and printed the Chat). Monday, I contacted Chat to have them removed the charges for HD on my current bill due Dec. 17, 2022 as I do no have HD. No help. Screen changed to "How to Request a Refund".
