Makro sold me a faulty fridge

I bought a fridge from Makro, via their online store. They delivered the item I ordered on time . However, the fridge was faulty from the beginning . It didn’t wasn’t as cold as it should be , even at maximum settings. It would make loud noises as well. I was naive enough to think I should give it time as I was probably over-exaggerating. I eventually got fed up and wrote them an email to explain why the item is faulty and should be looked at or at least I should get a new fridge . They took months to respond , after which they brought me a lousy technician from Hisense , who Told me the fridge needed more gas. He added so much gas to the fridge that it made situations worse. It would get extremely hot on the sides , and there was a layer of ice forming by the freezer doors . During the warm months , the ice would defrost , hence my fridge had a “leaking” situation now. I called and emailed countless times and they’ve brought me more Hisense technicians that I can count. What’s worse is every time I call and give them my reference number, they act shocked and unaware of my situation ... which had been going on for the entire 2019. I am disgusted by their customer services and management . They have absolutely no respect for customers and their concerns .
