Bad and no service from Makro

I am having such horrible service and being ignored by Makro! I bought a stove on 8 June online with a promise to deliver between 7-10 working days. This took way longer the promised, stove was delivered Ether 19/20 June... I only for it to be the wrong stove. This was me ordering the wrong stove. However I took it back to A store, Makro Pietermaritzburg and they said they cannot take it back because it is a third party company item and a call would need to be logged for it to be collected.

I then logged a call and this guy at Pietermaritzburg Makro logged as well. However it is now 17 of July and have spoken to many and emailed many at makro with no replies. The people I speak to and my wife speaks to, promise to get back to us immediately but No body ever does. I bought this from Makro's website which makes it there problem, I did not by it from another companies web page. I have emailed all these (Makro Customer Services, Jeannie Faulds, Strini Naidoo, Jerome Tommy, Lettisha, Moonsamy, Sanele Mpontshana, Bukelani Mbele, Bhekinkosi Ndlela, Komaran Padayachee) people and none of them got back to me.

I do not know what to do. I have moved from Western Cape to KZN, me my wife and 9month old. Can someone please help?
