Staff attitude and staggered shop

Went to FX on Monday 18 May and did a purchase on my card and left. Went to Foschini also in the mall on Wednesday 20 May made another purchase on my card and there the lady who helped me told me that I must go to FX to go collect my new card all old cards should be replaced. I went to FX immediately and found a staff member on the phone busy with another client also changing her card. She called her colleague to come and attend to me as she needed to go to lunch. Gave the phone with the guy of ?head office on the line for her colleague to help me. she then attended to another customer who made a purchase..I immediately got the idea that changing the cards was a huge hassle for them As the lady who helped me was the same one who helped me on Monday. I just felt why did she not tell me to change my card as the system prompts them to changed the cards. They are not a friendly bunch and the shop is always staggered and not client friendly like their other branches I visited before.
