Defective products!!!!

Bought 28 litre Bennett Read microwave from Makro on the 21st of August 2022, 3 November the microwave is no longer heating food up. Prior to this it would take one up to 5 minutes to heat up even a half a cup of milk. Took it back to Makro , they insisted to take it in for repairs. Repairs for a product that was only used for the 2 months? Well we understand the warranty and guarantee stories but just 2 months? Makro is aware of the issues with this brand but is still selling defective products!!! All I wanted was my money back but clearly, Makro and Tevo have deals on to **** customers!!!!!!!
