Edgars not accetpting an online purchase return.

I bought a foundation from edgars online, I recieved an incorrect colour shade, when I returned it to an edgars store in zevenwacht maal, I was told to take it to Somersaet West mall or to Tygervalley Mall, I told them I will not do that as the edgars policy says an online item can be returned at any edgars store. they called a manager (Meagan) for me who told me she willnot take the foundation because i did not buy it from them. i told them the policy says i can return it at any edgars store, she was not apologetic and when I told her that, she said her name is Meagan not edgars and she is just an employee at edgars. i told her i will not go home with the foundation as it isnot what i ordered.
