I have said here before that TT's CS is much better than BT's because after a minute or so of TT you know they are awful but BT can lull you into a false sense of security that they are going to sort out your problem. Both are normally polite at the start but when they find saying the same thing over and over again is not helping the blood pressure I know what's coming. A transfer to a specialist which in reality is just an opportunity to cut off the call. I blame the system first and the operative second.
