Great information - when it arrives. Like a London bus some weeks you get no copy some you get two. When you ring to complain (which I have 3 times in the last 6 weeks) they have no record of your previous complaints, they blame the US post, they dont reply to requests to speak to a superior, and they wont credit you an extra copy. Basically taking no responsibility. I've had it. I'm discontinuing my subscription. There's so much you can get online why should anyone put up with old technology.
