NO GO Area:CNA carnival mall incompatible

I went to CNA carnival mall one sunday afternoon, on my arrival I went to the tills ( where the security lady and the teller where having their conversation) ask them to help me with certain reading material for myself and my son, the security lady directed me to a children's isle where I went only to be more confused . I then went back to the tills and ask if anyone can be able to assist me because I cant seem to find a particular book , the security lady tells me " no one can assist, we are short-staffed , go at the back and look for a guy who will assist) I tell her I'm from the back and could see no one . Is it possible for the teller to check for me if they have this particular book I ask... my goodness the two lady continue their conversation as if they not hearing me, so I continued to ask if they can be able to assist me as im really becoming so annoyed, the security lady then tells me if I cant find what I'm looking for then it means they wont be able to assist. I ask her why did you direct me to children isle if you say you , but now you say you dont even know the material I'm looking for?yet you refuse to even look in your systems where can I find it...this led to a heated argument , I ask to see a manager . My goodness the security lady could not keep quite, i ask what her name is she tells me it's not important but her tag reads" Dudu Soko" . She has no manners , no respect to clients and even disrespect her lady manager. I told the lady manager it's of no use I remain here bcos even Dudu Soko shows no respect or any manners towards her . I have never felt so disrespected by someone who is suppose to serve as a guard within the stores and also show care to customers or atleast show that she values her job. Really she doesnt deserve to be a security guard for educational facility where we come for knowledge material, yet receive such an uncalled for attitude. My question is if shes serving as a guard, why is she busy mingling on things shes not compatible for. Such ignorance I pray i will never come across . Edcon please do something about this lady's attitude and reconsider her position. As a result I went to pNa, guess what ? They didnt have the book, they ordered it for me and today I just received my copy. Such great service from pna. No wonder CNA has less clients this days...
