worst service ever

On the 25th August 2019 I bought a AEG Gas cooker from Hirsch's and to my surprise the gas cooker started giving problems , in June 2020 the gas oven stopped working on the 24/07/2020 I contacted Aeg Electrolux and was given a service number by Beverley Makhene Ref 83-215724 two days later a technician came out to check the cooker and said that there is a major problem and asked was the flame always flickering like this and we said yes ever since we got the stove and we thought that's how it is , he advised that he was not suppose to be that way, the technician advised he will be ordering the parts and fix the stove. i received no update there after so i emailed Beverley again asking why has my stove not been fixed that was 8/07/2020 , i received a email on the 9/07/2020 where I was CC'd in with a Consultant Chanelle asking about my repair but i have received no response, i have tried calling but they answer my call and drop it. people do not buy AEG appliances , its nonsense and there service is the worst
