Clean Up My Account Details!

I previously had both a main Xfinity X1 XG1v4 box (Device Name Media Room) and a small X1 non-DVR HDMI only box (Device Name Basement). Last March, I returned the small, non-DVR box. It does not show up on my billing, however if I bring up the Support page (while logged in), on the "Your Service and Support" page, under the X1 TV, I'm still seeing a listing for the "Basement" device. The status shows "Status Unavailable", with an option to Restart TV Box.

Two days ago, I had a lengthy, very frustrating Chat session, with four different Chat agents. I was eventually transferred to a "Cable Specialist". After an extremely long chat, I was finally able to explain what I wanted (I thought!). I wanted the entries cleaned up, dropping the box that had been returned. I was finally told that by 10pm that night (call was in the afternoon), that my wish would be granted and the entry would not be there.

Of course, this time came and went, now two days later and it's still there. Who else wants to give it a try????
