After reading domex great reviews I booked an appointment my smeg fridge freezer had been overfeeding Engineer confirmed it only needs top up of gas but wanted £45.00diagnostic also £45.00+£25.00 in total £115.00 top up Of gas which doesn't come under a years warranty which is no different to refuelling a lighter of gas so no I would Totally say an absolute rip off to say the least avoid by all means
