SERVICE AT EUROPA ART SHOES AND FAULTY SHOES

I bought new pair of shoes from Europa Art Shoes Menlyn on the 30th of July 2018. I wore the shoes for the first time on the 12th of August 2018 for only few hours. The heel of one shoe got detached and I took them back to the store. All what I a was asking for was for the shoes to be replaced. The manager is refusing to assist and is insisting that it can only be repaired. I told like Hello Peter to please intervene because I feel my rights as a consumer are being infringed. I paid R 2 000.00 for a shoe that I thought it was going to be an investment. The Manager there Juvena was very rude and her management s****s leave much to be desired. I want the shoes to be replaced failing which I must be refunded. How can I be given second-hand shoes while I paid full price for a new quality pair of shoes. How does a manager tell whether a shoe has a factory fault or not? In my view her duty is to sell not to act as an expect shoemaker. I have been inconvenienced for the shoes that I paid for and this is unacceptable. I would like to request your intervention as a matter of urgency.
