Rude Manager

As spring was approaching I decided to get my self a summer dress and I came across a white dress which I bought,but because I was in a hurry I didn't bother to try it on,I just assumed it would just fit,but unfortunately when I got home it was not the case,I than decided that I would return It and get something else or buy my daughter something, today which is the 09/09 2017,I than arrived at the Mall of Africa to exchange it and we rudely told by Thembeni Qubekani,whom I assume is a manger there that how was he suppouse to sell the garment as puzzled as I was I asked him what he meant,he than showed me the make up Mark,which I didn't see,and told me Rudely that he can't sell this. My problem is not taking back the garment due to the make up mark,but of his attitude he is RUDE and has zero respect for customers.I got a mail from Ackerman to open an account but if that's how I'm going to be treated by Ackermans than no thank you,even tommorow I'm going to cancel my monthly laybye that I always have at Ackermans,Thanks to the lack of training Your managers about customer services you have lost a valuable and faithful customer,iv shopped with you since the birth of my daughter and that's the service I get.
