Getting the TCM channel restored to my service package

I have two DVRs with grandfathered cable card TiVo DVRs which were working with the X1 Preferred Pro service package and a sports and entertainment package add on.  On the 12th of November 2025 I made an inquiry to a Xfinity on line agent about a Gateway offer that was texted to me.  The live agent tried to sell me on getting the latest Gateway.  I wanted more detail about the offer before I made a decision but before the agent could provide me with the detail my internet went down and we were disconnected.  About 10 minutes later when my internet began operating again, I got an email with a change to my service plan which I had not authorized.  I got back to another Xfinity live agent and told the person that my plan had been changed without my authorization and I wanted my previous service plan restored.  The agent said it would be and confirmed it was restored.  However, the next day I no longer received the TCM channel.  When I went to a Xfinity service center and complained about the lose of this service I was told they could add the sports and entertainment package back on to my account so I could get the TCM channel until they found out I was using cable cards.  They were hesitant to add the the sports and entertainment package back on to my account for fear that because I had cable cards I might lose all my channels so we left things alone.  Tonight I tried to see if I had an option to add the sports and entertainment package to my account; but the option was not there.  I don't understand that if a week ago I was able to get the TCM channel, what has changed that keeps me from getting this channel again?  I now have the Ultimate package which I didn't authorize but is working fine.  Is there a problem adding back the TCM channel?  And if there is no problem, why can't I subscribe to the sports and entertainment package which I was subscribed to a week ago?
