poor customer service from Donna/Foschini at Baywest

I am only rating a star because I have to. On Saturday, 28 Sep 2019 I went to return 4 items at Donna at Baywest and then I had to wait for over 30minutes for someone to come and authorise the return. No one in the shop had the authorisation code and the one person that had it, Rene stepped to God know where and the staff member was calling to no answer. I called customer care to complain and when I handed over the phone to the staff member she said the supervisor was not gone for that long and that she whatsapped the supervisor to get an authorisation code. The code she got did not work on the system. I left to continue my shopping and returned an hour later and the supervisor was there, Rene. She was so rude and dismissive, she refused to help with the return because the slip I got from online shopping because it had no CR number and online shop was closed. I told her to phone customer care because they can help and she phoned but she told the call centre assistant that she cannot help me because my receipt had no CR number and hung up. She basically chased me away from the store, if there was a camera you would be able to see her waving her hands at me to leave.
