Horrible service from Foschini Sandton manager

Foschini Sandton manager services are horrible, I bought headsets this morning and I went to the office when I got there I realized the earphones are too big and they are not normal Bluetooth earphones, OK I read the back of the slip and I see I can return them because they are not part of the items that can't be returned like underwear fine I go back to the store when I get there I talk to Muhle she is the manager and she is rude when I tell her that she is wrong to say the document says I can't return. Now I am stuck with big earphones and a bad experience from a rude manager. I didn't know this is the type of service TFG promoted.
