4 SMEG appliances let us down and cost a fortune

We bought a 4 door side by side fridge in September 2019. It started giving issues a few months ago and the fridge would stop cooling. Smeg told us we need to replace the circuit board at quite a cost. Now the fridge and freezer randomly stop cooling and no one seems to know how to fix it. Despite call outs with technicians and the fridge being on backup power during load shedding it is not working. Our frother for milk is a year old and the paint is peeling off the inside of the unit. Our coffee machine’s display shows only the temperature icon, all the other lights stopped working after 2 years and the coffee filter had holes in it after a year and required replacement or paper filters. Our Smeg stove is peeling pains on the outside and it older so I guess ok but I have never had these issues with appliances that were much cheaper.
