Is your complaint that after you insulted a member of the broadband team, they placed a bar on your phone? If so I would follow the Complaints Review procedure. I'm a bit unsure of a few things, not doubting you its probably just the way you wrote it. Would a member of the broadband team be able to bar your phone? Can it be done that quickly? Also, the transcript of the chat is automatically sent, so why does it need to be sent again.

im going to follow the procedure yes, but i haven't got the transcript from my conversation with the member of staff that led to my phone being barred. is there anywhere on the O2 site i can visit my previous chat history? the transcript hasn't been automatically sent???
