Foschini is taking advantage of customers

On the 27/Nov2015 I bought the shoes for my daughter to wear on Christmas, she wore the shoes twice on Christmas and on the 2nd January the shoes were already torned as a result my child cannot wear torned shoes. I took back the shoes on the 11Jan2016 but the sales person by the name Maurin refused to take them back saying I should have brought the shoes back immediately she will not authorise it. I requested to speak to a manager, she said the manager is not available and she took a photo of the shoes. I came back on Wednesday she said the manager will be available on Friday she will ask her to call me because I said to her I won't be able to come on Friday.On Friday instead I got a voicemail from the same person Maurin telling me to come to the store the manager is available why must I come to the store and yet I specifically told her that I will not be available they should call me. I then call back and speak to the manager by the name Cindy,Cindy said she'swaiting for the store manager to authorise and she will definitely call me on Monday.It's after a week no one called me.Why did they make me to wait till Friday for a manager who cannot make a decision in the first place?
