Very rude and disrespectful

Today I had a bad experience at the store at Meadowpoint in Meadowlands from the staff member named Ayanda. I was busy shopping and she requested us to move because she wanted to clean, I told her to wait for us to finish but didn't want to, she cleaned on top of our feet and had the dirt of floor on our feet. When I approach her, she threatened to hit me with a stick and insulted me infront of the manager and other customers. The worst part is that the manager didn't bother to control the situation. The Ayanda woman didn't even use the Caution sign to show that she is cleaning and then she becomes disrespectful and had a very bad attitude. Where is the is customer care in that store?
