am writing to formally lodge a complaint regarding a Defy stove that I purchased from House & Home to replace my old stove, which had reached the end of its lifespan. Unfortunately, since installing the new stove, it has been causing damage to my kitchen unit. I visited House & Home to report the matter, and they contacted Defy to arrange for a technician to assess the problem. During the inspection, the Defy technician explained that the stove does not have a cooling fan and indicated that House & Home should have informed me of this limitation before I purchased it. The technician further advised that I would need to modify my kitchen unit to accommodate the stove and prevent further damage. My concern is that I used my previous stove in the same kitchen unit without experiencing any problems. I was not informed at the time of purchase that the new stove would require modifications to my existing kitchen uunit.When i go back to house and home they said they cannot do anything. I believe this information should have been clearly communicated before the purchase, as it would have influenced my decision. I am therefore requesting your assistance in resolving this matter by either: Replacing the stove with a suitable model that can safely operate in my existing kitchen unit without causing damage; or Providing a full refund, as the stove is not suitable for my current kitchen setup.
