Frustrations Over Technicians who Can't fix the Fridge and Requesting New Fridge

I would to express my disappointment towards Defy. I wrote here on the 23/12/2022 complaining about the poor service from their *********** Technician who are failing to fix my parent fridge which we bought for them with my siblings as a token of appreciation towards them. I curse the day we bought that fridge because from December and I have called Defy twice. I made a call on the 14/04/2023 with Job Ref no. *** and technician came fixed then ended up making abnormal noise which I reported to the guy Carsten which he promised to send technician for assessment which technician never did. Carsten refused dismal to understand why we are requesting a new fridge instead he asked me where did I bought this fridge from. He explain to me how he will not give me new fridge because 6 months has passed. I'm so frustrated because he requested to see my uncle who bought the fridge for us as we wanted to suprise our parents. As from today fridge is not working and my uncle went to report it on the 15 May 2023 as Carsten advised on our previous discussion, Ref no 180267. Technician came at home on 16/05/2023 but had loadshedding and he promised to come back today which he never did with no update. I'm so frustrated because we did not buy fridge to call Defy every month and we bought it because we regarded Defy as a reliable brand. I'm requesting for top management to intervene and give us new fridge because I curse the day I chose Defy. Your technicians are not fixing the problem instead they pouring boiled water at the fridge or ask for hairdryer since its not freezing on the freezer and due to that now fridge has developed abnormal noise sound. Please top management intervene.
