Very bad service

I am very unhappy with the service given by Matsidiso at customer service. I wanted to exchange my son's pants as they did not feat him with the right size and the pants had a swinging tag but no receipt. The cashier called her for assistance and she came and told me that she cannot exchange as the cannot locate the store where I bought the pants. I was puzzled as this is not the first time I exchange without a receipt. She just wasted my time and other customers in the queue. I ask her to give me back the pants as I will exchange it at another Woolworths and I will take this matter feather then she said that she will assist out of her will. I really don’t understand if Woolworths assist under staff or their policy. I then call the store manager and they said the manager is not in and none of the staff on the call wanted to take the responsibility they then took my numbers even today I am still waiting this happened on Saturday the 05 April 2025 around 13:00 you can view the DV(camera) to see how long I waited this is really unacceptable.
