Timeslot for delivery of new cooker was given as between 11am & 3pm, would receive a phone call when driver 30 mins away. So they arrived 10.25 and without a phone call. They disconnected & removed old cooker, tested gas supply. Then advised they can't install it due to where it was to go (despite having just removed the old one from the same place). Brought the new one in & left us with it. At least they arranged for the installation charge to be waived. Took most of the afternoon, but I unpacked & fitted it myself. Seems rather strange that it was not an AO van which brought it. No advertising there. Did they not want to fit it so they could finish earlier in the day? Tend to wonder, as some friends had the same experience only 2 days later.
