Poor service

My husband bought a Sylver CREST XXL digital airfryer. I cooked with it and I was not happy with it. It is very slow compared to the Milex airfryer we have, I told him tor eturn it. I washed it and one of the icons started to fade it gave more reason to return it, poor quality. Now takealot doesn't want to take it back saying it was used, how would I have known that it is slow if I did not use it. They claiming it has a dent of which it was not there when I packed it. First time I receive such poor service, I am disappointed. I am so done with takealot.
