Makro just don't care about their customers

I bought a food processor - box was taped and closed- when opened part missing, no manual and seemed to be opened before- took to returns- lady told me no one at store to get me another unit- there was a box on shelf- also half empty- I took part and manual from the demo model and decided to keep my food processor- i went back to returns to find them closed 06:05 - Information desk advised they shut down already must come back again-3Rd time!!! Now I have to take leave and go back again- MAKRO is not client centric at all - how can they treat the public like this? why did they not stay with me until I was satisfied or helped? The returns are stacked up and half opened / used products on the shelf- I ask another 2 people who the manager is- they said manager left already- did not ask how they can assist or anything - no interest in their client at all
