Pick n pay bad customer service

Bad customer service i got at Pick n pay Northmead mall, i went there to buy washimg powderi was helped by Mbali Nhlapo then behind her there where two ladies so they started making remarks about my body laughing then the supervisor was like pls stop body shaming, i was disgusted by old woman's behavior. As a person who struggles with weight who is going through therapy becausw of weight they triggered something in me now i have o go back to my low self esteem becuse of them. I am so sadden by this why couldnt wait until i was gone to start making those remarks
