Tivo will not remove Premiere I sold from "active devices" list, why?

I emailed Tivo this morning to remove Premiere box I sold from appearing my Active Device list when logging into Tivo.com.



They replied to my email saying they can accommodate and to call customer service.



Customer service then says call tech support. Tech Supports says they can't fix the problem.



I am really mad about lying to me and then the lack of customer service!!



Is there anything I can do here?
