Hi @getmellow and welcome to our Community Forums.
I've looked into this for you and have raised on your ticket in regards to the removal of your BT sports Add-on. If you can please confirm you wish the Add-on is removed via this ticket here then I can action this cahnge for you.

I look forwards to hearing from you further.
