Pick 'n Pay - NO REPLY

I had an incident at Pick 'n Pay Canal walk a month ago. On the day of the incident, the store manager, Linden, asked me to send him an email so that he can take the matter further. I sent the email a few days later, on 2nd March to Linden and then again to the customer service email on 5th March 2021 - just incase Linden was on leave or away from the office. It has now been a month since the incident and NO ONE has acknowledged my email or made contact with me. Yesterday I went back to the same Pick 'n Pay and was assisted by the same cashier - Zukiswa Tebekweana. I watched her deal with the elderly gentleman who was ahead of me and the manner in which she spoke with him was simply, not nice. She has an attitude of note - one that screams 'the universe owes me'. In my interaction with her, I decided to test the waters and asked her if I could get cash as well. She looked at me and said 'Well I dont know if there is enough cash in my till. You will have to wait on the cash office to bring money. Are you waiting?' This woman needs customer service training. I would expect this kind of attitude from a youger, 20 odd year old person and not from a matured woman! Let us see if anyone will even respond to this.
