Rudeness and Dimining tone- Attitude is everything

On the 20th April I went to Pep stores at Tsakane Corner to apply for a Capfin loan for the first time. I noticed that Ntombifuthi the consultant that assisted me had scanned the 2 older payslips that I had and forgot the latest one, but I couldn't say anything as I am not sure how these things work. After she was done I left and went to another store that is when I recieved an sms saying I need to go back to the store as the documents were outdated. After I was done I did exactly that, I went back to the same consultant and informed her of the sms POLITELY might I add ( I work in client service so I am fully aware that we sometimes make mistakes). The consultant was mopping the floor at the time and the manner in which she addressed me I did not appreciate saying that I gave her those documents it's not her fault it just means my documents are old. I didn't want to argue and asked her if she help me apply again when she told me I'll have to wait for her to finish mopping, which I did. After a few minutes she came to my aid, I told her I think she made a mistake with the documents hence the sms, she continued to tell me not to argue with her because she did everything right
