My oven is less than 4 months old needs a new seal for the door, had to try to call customer service got cut off 3 times once I know was deliberate as she forgot to mute her mic said oops giggled then I get a dead line! Phoned head office to be told that high winds could have cut me off yet was on the phone to there HO for 40 minutes! (There ho is the same building as there customer service) they wanted 99 pound for a callout to a oven that's less than 4 months old! Utter joke im off to trading standards first thing! CDA avoid at all costs
