Question Author
Thanks for the information, iwalec. After I posted the question I found a website (which I have since lost) on which someone asked a similar question and received many answers,ranging from satisfaction to complete disatisfaction, and plenty in between. BTs Indian helpdesk somehow crept in to the discussion - I could identify with this as it took me five weeks and hours of adjusting programmes as they sugested before they discovered that someone at BT had incorrectly connected my email so that it didn't work!
