Poor quality product and service from AVO and Hirsch's

I bought a Defy microwave oven in December 2022 via the Avo Nedbank app from Hirsch's. It initially arrived late January (after many follow ups from my side) but with dents on the top of the microwave. It was returned and a new one delivered in February. (Note that this was a Christmas gift for my mom). In September my mom complained that the food is getting burnt and the containers extremely hot when she uses the microwave oven, even for a few minutes at a time. I informed Avo who arranged collection. After 3 weeks I still had no response, no communication, not even a collection note was provided to me. Then I received an email stating the microwave is on its way back, not explaining what was wrong, what was fixed, or any sort of report. I phoned Hirsch's Edenvale directly and Casandra promised that she will obtain a repair report from Defy and send it to me. I am still waiting for it. The day the microwave oven arrived back, we opened it only to find the steel panels were bent and not properly closed, therefor not safe to use. I have logged another call with Avo and it's now been almost a week without response from anyone. I will not recommend it to anyone to buy online from Avo or Hirsch's. My personal opinion is that this was a reject or demo microwave sold to me.
