Brand new faulty appliances

I bought a double door fridge,34l microwave and bulit in slim line stove set at Makro Wonderboom.The fridge has been repaired twice(not freezing),stove once(one plate not heating),microwave twice,its not heating(its at Makro now waiting for service).I am really dissapointed.What is going to happen because they will be out of warranty soon.I feel like i have wasted my money.
