Worst service ever!!!!!!

I ordered two bar stools online from Makro. When I opened it the base of stools were scratched. I returned both chairs via the Makro online platform. I asked for the chairs to be replaced. Makro collected the chairs. A week later I received the same two chairs in a new box. Again I emailed Makro and told them that the chairs was not replaced and that it is the same chairs with the exact same scratches. I have now phoned twice and emailed Makro about 4 times. My emails does not get answered and when I phoned them they could not assist and keep on referring the matter to a different department. I requested a phone call from this department. No call or email received. It seems I am waisting my time to phone or email them. It is totally unacceptable and the worst service that I have ever received. My makro ***
