I usually call the international line 01332 XXXXXX as it doesn't cost anything from my mobile as opposed to the 0845 number. Find there is no difference in service. I get the impression when you call any of the lines you go through to the same bunch of people who probably have blue, silver and gold lights that light up according to what number you ring and they read from the apropriate script. Certainly I have spoken to the same people if I have called the international line as I have calling the gold line and you get the same odds of getting a good helpful agent or an unhelpful one that tells you computer sasy no to every request.
