Makro has failed the ordinary customer

I bought a hp printer from makro (Springfield, Durban) in March this year, ever since I have started using it I have been having problems, I have been to makro couple times stating it's not connecting, etc etc, however I was turned away from their returns counter, (please note I did not go to return the printer) they even told me why don't you fone hp support, & they even gave me the number which connects you to the call Centre in Tunisia! or take it to hp it ensure, I went about 4 times to makro, to which I was sent back home with it, by now I felt highly embarrassed to complain & called the call Centre, they tried doing the troubleshooting & saying take out the plug, replug in, eventually she failed so she tells me sorry you have a hard drive issues, take it to ensure it, to which I did, fast forward I picked up the printer from it ensure, & the nightmares continue, paper is only jamming, it's not printing well, so I take it to makro once again, same scenario plays but I stood my ground, reluctantly very reluctantly the lady books it in, sms comes, part to be replaced another 10days gone, I pick it up after repairs I realised the wrong box was given, tried to connect to my wifi, it's not connecting, makro is not interested in solving the matter, I have emails with proof from customer service of the unit giving me endless problems, all I ask the unit to be replaced or my money refunded as we can see, within 8 months two major components being replaced, unit is hardly used, is it too much of an asking, one salesman asked me how can I help you when I explaind to him my situation hes attitude changed, I asked to speak to the manager higher up, floor manager said no chance, it has to go through me, I have observed when you walk in to buy something they all hound you when you have a complaint they snarl at you, is this the makro I know as a valued customer for so many years? This is my last attempt, even makro care does not want to assist any more!
