Pathetic service

2 weeks ago we called because for the 2nd time in 1 year our stove broke AGAIN, we have been going back and forth for the last 2 weeks because they can’t understand when we have been telling them that we dont have the slip because we had it installed over 2 years ago by a guy we used for our renovations!! Defy has the proof of purchase on their system, on a previous ticket, but no one can use their brains to go and check on that ticket number!! Every year this thing breaks because of **** quality parts that they install! We had it replaced twice in the last year and a half, its pathetic that they keep on hammering on proof of purchase when they can clearly see its **** they installed! I would never recommend to anyone to buy any defy appliance
