38 week pregnant mom gets disgusting service from Jet Parow

Good day today I was in Jet stores with my father and fiancè. My father went to activate his account today myself and my fiancè went with him due to my father is old his over 60 years old and my father can't communicate probably and sometimes doesn't understand properly that's why I go with him to assist him and making sure he understands what his signing up for and doesn't sign up into unnecessary stuff. However my father was put on the phone and had to answer security questions over the phone due to his greenbook ID was too old but my father failed the security questions and was adviced by Emma the old lady to bring a new bank statement and ID so that it can be scanned. However I asked her how long will this process take after the scanned the documents will it take a day or week? And her reply was I don't need to be sarcastic and I'm not the customer so she don't need to answer me if I have any questions I must ask my father. Then I told her but I'm his daughter and I'm the one making sure his doing everything right but she's just like standing her ground I must ask my father with a attitude. I didn't still go back and forth with her I just told my father let's go get the bank statement by Capitec and come back. We left and came back then Megan September assisted my father very nicely I must say everything went smooth. So I went to Emma the old lady to talk with her on how I felt and that I didn't appreciate how she spoke with me. Then she ask me did I come all the way back to the store to come her that but with a attitude. And also judged me on how I look, I am 38 weeks pregnant I don't care how I look comfortability is now my main priority but then things escalated and I raised my voice at her. Because she doesn't know how to talk to customers, she's rude, she has a attitude and she's very judgemental. Just because she's older then me doesn't mean she can talk with me however she feels like it because I'm not her child, I am the customer whether I'm a paying or a non paying customer it does not give the right to speak to me and any other customer in that manner. I will rather stick to Ackermans and Mr Price for myself and children for clothes. I am utterly disgusted by the service I received from your staff member Emma. I hope the area manager does something about it too improve the service in the store, also non of your staff have a name badge on.
