My apologies for the delay in my reply, the CS&B forum has had limited support over the Xmas period which has resulted in a backlog of posts.
Im not sure there is anything for me to address in this thread. As you have privided the link for the change of ownership form, you jsut need to print this and send it in to TalkTalk for the change of ownership to be completed. This can taken around 28 days to complete. As you have advised a seperate procedure exisits in respect to bereavement.
