Defective Merchandise - No Resolution

I bought a pair of slippers for my daughter from Woolworths Cradlestone. After only wearing it once, we noticed the slippers were torn. I took it back to Cradlestone a week later and the customer services manager, Ms Sibongile Moloi, refused to exchange it for us. Instead she opted to send it to a textile technician, I am not sure what will be achieved by this. To date I have not been contacted to explain whether or not the shoes will be replaced. I have been a faithful customer of Woolworths since they started out in South Africa, but I have never experienced such terrible service. It seems Woolies is losing the plot.
