Poor customer service

I bought a set of balconet bras on the 14/04/2021 at R199.95. I wore the bra ones and one bra had aquality default, I returned both bras for an exchange but the manager by the name of Eugene approached me with an attitude telling me she won't be able to do an exchange for me because I have worn the bra. I told her the bra looked ohk when I wore it I only realised later when I took it off that it has a quality defedt her response to all that was due to the fact that it was worn she won't exchange it for me, I then asked her if the quality problem was my fault she then walked away. I asked her to give me her name and their customer service number she said I'll find the numbers on the receipt. I immediately called their customer service to respond the incident but to my surprise I got the same attitude and response, the customer service assistant told me that her manager says they don't exchange underwear despite the quality defect. I'm so angry with the service I got at Ackermans. This incident happened at Ackermans Hammanskraal Renbro.
