Quality of jersey from Queens park not accepted

I bought 3 men's jersey at Queens park Kollonade on 21/06/2015. My dad put the jerseys on to check if they fit him. The two jerseys were fine but the 3rd jersey had loose wool sticking out at the back then he took it off so that we can return it to the store due to quality issues. I took the jersey to Menlyn Quespk on 29/06/2015. I wanted to exchange it for another type of jersey but the sales lady refused. We argued for almost 20 min and my main emphasis was the quality of the jersey that's why I wanted to exchange it. the sales lady indicated that the exposed wool can not be regarded as quality issue and only if the jersey had holes she would exchange it. I asked to talk to the manager ,she indicated that she is the manager. Her name Kate M. Then she decided to consult with someone at the back of the store. She came back and said that someone advised her to take the jersey and send it to Cape Town for quality check which for me sounded ridiculous so I decided to keep quiet because I didn't want to argue anymore. She said it will take two weeks. I don't need the jersey anymore so Queens park must please credit my account for the jersey because I will not accept bad quality.
