With in 3 weeks i have been through 3 cookers now we are waiting for our 4th one to arrive fingers crossed this one works, the first one was admitting orange/yellow flams on all burners and the oven packed up after 20 days, 3 Ao engineers and one smeg engineer came out failing to fix the problem, AO finlly deciced to replace it for the 2nd one where the AO installers eneded up damging the side of the cooker leaving 3 medium size dents and i dont know how but they also managed to bend all the feet on the cooker the worst part was how they tried to hide the damage by leaving the blue protection film on until they pushed it to place i was lucky that i was watching them and noticed the damaged. So i was back on the phone AGAIN to AO with another wait time of 40 min wasted as they had failed to call me back to arrange collection/delivary date...7 days later the 3rd cooker has arrived and this time me and the engineer checked it over for any damage before installation once it was installed the engineer turned the oven and we herad a bang and the power went out tripping the RCD switch the engineer arsured me its just a blown fuse in the plug after replacing the fuse we turned on the oven again and did the same. I can't express how fustrated i was by now as i'd have to call AO again and waste another 40 min in the cue but yet if you call sales the waitime in only a few seconds LOL. customer service then told me they were out of stock and that it would be back in stock on the 28th Sept where AO would call me and arrange a new delivary date for the 4th cooker...you guessed it NOOO call back so called them today only to be told there very sorry but they are out of stock again and will be bk in on the 7th Oct.....they had stock yesterday tho :(
