Staff need customer service training

I am disappointed by my experience at CNA Sandton today. <br> I bought a laptop bag 11 days ago. The zipper on the bag was faulty so I took it back to CNA for a replacement. Bag was unused.<br> A comment made by your staff at the store today shocked me. A few months ago I purchased a printer/bag/mouse combo Within a couple of months the bag started to unstitch. I took the bag back and got a replacement. <br> When I went in today, one of your staff suggested that this was becoming a trend and that I had been there before to replace a bag, suggesting I wasn't entitled to this replacement! <br> He did not have his facts right.. These were separate purchases, and different bags. Instead of CNA addressing the quality of products you are selling, your staff rather suggest that customers are the problem? This is both unprofessional and absurd! I did not cause damage to either. I merely returned faulty items<br> <br> Needless to say, I decided not to exchange the bag anymore and got a credit instead. I was extremely embarrassed and humiliated by the treatment. I am not in the habit of damaging goods and returning them. I don't have the time. Please train your staff on customer service. I am appalled!
