Bad service from Store Manager

Good day, I have just arrived from Christiana Ackermans and I must say I am very disappointed in kind of Customer service I have specifically received from the Manager Jane Sehako. There were two items I needed to be exchanged as I have bought them on Thursday at Ackermans North Cape Mall and unfortunately it didn't fit my kid when I got home, however when I entered Ackermans Christiana I met with her at the door and explain my situation. Instead of a proper customer service she altered words to me by saying "you guys buy stuff at different stores and expect us to assist you". I am very disgusted at her behaviour as it shows how little she knows about Customer service, did she even do induction? The cashier Martin Seboletswe was more remorseful and helpful and even apologized for his managers behaviour. I am urging you as a company to fix this problem cause as a client I can't imagine what customers has to go through in this store just to receive excellent Services. Thank you
