Mark, going back to your earlier post about the pump only lasting 3 months and they wouldnt repair it, it has to be fit for use, and is covered by Consumer Rights surely.
How did you pay for it, if you used a Credit Card, and you paid more than £100.00 (might be £50) you are covered by that, get them to fight for you or just ring up your local Trading Standards office and they will advise you.
If my friend in Trading Standards buys anything for more than £100.00 or substantial she allways allways puts the deposit through her Credit Card. That way she has got them on her side if there is a prob. Thats what we do now, probably the only good thing about Credit Cards I can think of actually.
