I have been trying without success to remove the BT Sport Second box from my account as it is no longer used. The only options I can find are to cancel the subscription itself, which I don't want to do as I want to keep the BT Sport in the main box I have. When I try and modify through manage extras in my online account it just tries to get me to add on the HD pack and doesn't give me the option to remove the second box. Does anybody have any ideas on how to resolve this, preferably without having to call through? Thanks in advance.
