I had a Rangemaster oven and hood installed in October 2016 as part of a kitchen refurbishment. I registered online on 1 November 2016 for an extended 2 year warranty but this appears to be ignored by Rangemaster. The stainless steel rangehood now has unsightly marks on the front and on 9 January 2018 Rangemaster sent a service technician to inspect. He declared that the problem was not due to the cleaning of the hood and he was unable to remove the marks. His report went to Rangemaster that week. After hearing nothing for 2 months I contacted Rangemaster who declared the file was complete. I asked them to look into it again and they then said the service technician had reported the hood as "unrepairable". I was then told by email that Rangemaster would look into exchanging the hood and then a further email said their technical department had decreed it was not a manufacturing defect and therefore it would not be exchanged. I again asked Rangemaster to look into my concerns and after providing photos on 3 occasions they sent me a further email on 12 March 2018 with tips on how to clean the rangehood. Rangemaster's website gives 3 different email addresses on how to lodge a complaint with automated bounceback messages detailing how long it would take them to get back to me (ranging from 1 hour to 5-10 days). I have corresponded with all these email addresses (the last being to head of customer services on 4 April 2018 with a response time of 1 hour) and to date have not heard anything further from Rangemaster. I expect they are hoping I will go away. Any suggestions on what to do next would be greatly appreciated.
