I have unfortunately lost my slip, but have a mini statement showing exactly when i purchased the shoes the reason i need to exchange them is because they are broken and i have no joy from them the answer is “we belong to Foshini now and cannot help” i have never seen anyone be so unhelpful ever. This has happened before with other retailers from Nike to Mr Price but never was i turned away. I paid for the shoes from your store and now you expect me to keep the broken heels! How is this acceptable just because someone is to lazy to check their system and using a terrible excuse aswell!
