Bad service at Mr Price Home (Centurion mall)

I am not happy with Mr price home (Centurion mall). Yesterday I came to buy a duvet set and they only had one left which was a display and I requested to buy the display but was told that the lady who works on the duvet section already knocked off. I was then told to come the following day which I did and when I got there, they took out the duvet but couldn’t find the pillows. Apparently the pillows were given to another customer who came and complained. I requested to talk to the manager and she came but was not interested in talking to me. She only spoke to the consultant and told her I can only buy it without pillows but the amount will remain the same. She didn’t bother to come to me and explain other options or how we can go about the situation since I was told to come back again the following day.
