Unprofessional service, stuff sent is incorrect, staff are rude and very disrespectful

So I purchased a candyfloss machine from Takealot. I received the machine the Saturday, and used it once. The second time using it, it was not making candyfloss at all. I never unpacked the machine, without me knowing not everything was there. So the machine supp**** was incorrect. When I logged a return request I packed the machine and then I realised that it was incorrectly supp**** I done this in the 7 day return policy. I also made it known to them that what they supp**** and according to my order it's incorrect. I then got a disgusting reply from one of Takealot's staff members and I was told that when I opened the box I should of let them know so they won't be sending me the correct item, so according to Takealot the machine has got a warranty, then with the machine not working I got told by the staff member I voided the warranty because I used the machine and I damaged it. So they will not be replacing it. I then caught this staff member on his/hers lies and then all of a sudden it was a misunderstanding and apologiesd. Then I was told I will be getting a new machine and the one I ordered originally ordered I even have proof of it. Now today I received the new machine but again I have received the incorrect one. I honestly don't know what to do anymore. This service is completely and utterly disgusting.
