Rude consultant

I am very disappointed in the kind of service I got from your gateway store on Friday 3/05/2019 at the Info desk when I went to enquire for a size, a lady by the name of Cornelia who assisted me gave me attitude because my baby was crying and she was on a call so she just told me that my child is making a noise and she cant hear her customer. I wasnt happy with her manner of approach to this situation so I took it up to her manager Nosipho who then asked that she comes and apologise but she refused.
