Disrespet and unprofessionalism

Dear Dischem I've just encountered one RUDE manager at Mall Of Africa Dischem . The Cashier P Mahlangu was helping me to change a product that I bought . So now she calls her manager to do help with the void and she was sooo annoying rude to her . I asked nicely to talk to her and I told her I didn't like the way she spoke to her and she said she didn't say what I heard her saying and she just walked away saying that she is busy and she is the only one on the floor assisting everyone and I could see that she was annoyed so I decided to keep quiet. But she still was mumbling defending herself to the other ladies . I asked her name from the cashier and she no it's okay . After all the talking I decided to walk away. Am so annoyed of her disrespet towards the lady and her unprofessionalism .
