I was so chuffed when i bought a brand new integrated multifunction microwave oven for £150 from a lady in Plymouth through FB marketplace (half new price). She had bought it as part of a new kitchen but didn't need it. My kitchen extension was substantially delayed & it was 6 months before my electrician was able to fit said oven. All of the digital controls etc worked perfectly, BUT it didn't microwave or heat up. Over Christmas this provided a brilliant distraction for visiting family and friends, who studied the manual, determined to find the button to make it work ...which they never did. My electrician upon recent visit had a peek inside & said it was not wired up & there were substantial parts missing in order that it was to work as an oven or microwave. He suspected it was a 'show' oven. I contacted the lady & asked for my money back (in return for me delivering item in same condition i purchased it). She refused & said that no shop would give money back after 6 months. I said this is irrelevant as no shop would sell an oven that didn't have the capability to heat. She immediately exited the 'chat'. I just wouldn't be able to sleep at night if i had ripped someone off like this (regardless of whether i knew or not?). Is it unreasonable to expect my money back?
