Poor quality of goods and really poor customer service

I spent R4999 on an account i am still paying off for an office chair that keeps sinking down. I called Makro and a guy named moses started helping me and it took a long time before someone came to help look at the chair but it was not even from the right company. I was told someone from the right company would come to me and its been almost 7 months and when i email makro my emails either get deleted without reading or ignored. Makro are selling inferior products and cant even give propper service when the **** they sell start malfunctioning. Like who still sells celeron computers.. I have my own IT business and the latest stuff is i3 i5 i7 they still selling celerons ripping people off
