Makro online faulty appliances not resolved

I bought some kitchen appliances online in April 2019. 4 of the appliances are faulty. I have logged many complaints online and via their call center. Every time I speak to them they have a different person, different excuse, different protocol, etc. They are just not taking responsibility and getting on with the job of dealing with the faulty appliances. I am passed from one person to another, but everyone says that they can’t make a decision. It have been trying to resolve this matter for over 2 months!
