Edgars Zevenwacht not accepting a return

I bought an estee lauder double wear foundation from edgars online and selected store collection which i collected at Edgars Zevenwacht Mall. I received an incorrect colour shade. When I returned the goundation at Edgars, i was told that I need to take it back to edgars Somerset West or Tygervalley and I told them I wil not do that because the edgars online purchase policy says you can return an item at any edgars store. THey then calle dthe manager who is Meagan who did not evenn acknowledge that edgars was at fault for giving me an incorrect colour, she said she is not edgars and only works for edgar. i told her I will not take the foundation because it is not what I ordered and what I paid for. She has not customer service ethecis, did not even apologise. left the foundation with her as I told her i can not take it back because it's not what I ordered.
