Disgusting service from DEFY

I bought a Defy oven and stove on the 30 June 2019, in March 2020 the one plate didn't want to get hot and the oven door didn't want to close properly because Of COVID I couldn't report it, in June I reported it and Defy technician came made adjustments and replaced the plate. (Ref No: *** / ***). Not even 2 weeks later and the oven door wasn't closing properly again.

Then the 05 November 2020 I wanted to use the oven and the thermo fan was making a noise, so I reported on the 06 November 2020. The Technician came out on the 12 November 2020 and said that the thermo motor has stopped working and the hinges needed to be replaced, I tried calling the call center agents to see what is happening and all they can say is the parts are pending, I then asked to speak to the manager but she is either working from home, discussing the issue or in meetings. I called again asking to speak to her manager and the Call center supervisor took the call and promised to call me back with in the hour, well that didn't happen. I called head office in Durban on Wednesday morning and the Lady said that she would have someone call me back urgently. I finally got a call where this person said he promises on Friday 04 December they will be at my house to fix my brand new oven that isn't even 2 years (Ref no: ***), it is now 21h30 and defy has not come. unless they changed there hours to 24 hours.
