No, not now. I had trouble with Demon years ago and finally gave them the boot and went across to BT. Never had a problem since. For some reason I was finding that I couldn't log on from time to time. When I used to phone them I had to keep trying for about three hours or so, (shows you how busy the helplines were) before I could get through to them. This used to happen on a regular basis and that's when I decided to go across to BT.
