I've just checked the Currys website online, 1 hour mate, they've mugged you off for the reason I said.
Sucky's gone quiet, bet he's fooked off to the shop now, to buy stuff for the fridge he's just turned on.
Probably left the poly round the gas bottle, driver comes back and makes Sucky look a dick by taking it out.
Ive just read the whole manual and it don't say a fuking thing about not turning it on for any amount of hours never mind 8
did in the one i had a couple of months ago but it was nothing like 8 hours . You sure you didn't call them slow ****s before they even got it out of the van
