Poor customer service and faulty products

I bought a defy stove from Makro in May 2021, the stove stopped working end February 2022. I called Makro and they referred the matter to Defy who then sent a technician to come and fix the stove. The stove only worked for a month and a week. It stopped working again on the 12th of April 2022. I had to call Makro again, just like the first time they referred the matter to Defy. I got an sms with a refence number, it indicated that Defy assigned a technician on the 14,the technician wsasa supposed to come through on the 19th of April 2022 but he never did. I had to call Defy and was sent from pillar to post. I was told the technician will call me shortly to set up and appointment and come through but still he never called nor showed up. I called again on the 20th of April 2022 and they said they will escalate, when I checked the status on the sms it indicated that the technician will come through on the 21st of April 2022. I had called Makro as well on the 20th of April reporting that their Defy people are not responding to the matter. The lady from Makro told me she will have to call Defy to follow-up to hear what transpired and will get back to me. Today is the 22nd of April 2022, i am still awaiting the lady from Makro to get back to me, i am still awaiting the technician to come through. It's over a week now with no stove, I can't afford take-aways anymore. What kind of a game is Defy and Makro playing? When i called Makro i suggested that they replace the stove coz it's broken for the second time in just a month after it has been fixed which makes me believe its faulty but I was told onky Defy can make that recommendation for replacing or refund. I am hopeless, stressed and frustrated. Is this how Defy and Makro treat their customers? I regret shopping at Makro, I regret choosing Defy out of all other brands.
