glad your all fixed up now Jeza don't mention the ironing though.
I would send the bill with a covering letter to the MD of Currys and by recorded delivery. keeping a copy for yourself, you can but try, also The crusader in the Daily Express will sometimes help. If I can find the e mail address will post it in here for you, but go to the very top don't bother with the middle man they cannot make decisions. No harm in trying. Next time try AO company for appliances I found them very good and true to their promises redelivery & timings and they had a spare hose on board no extra charge.
