Utterly Disgusted at PnP Cleary Park

I am utterly disappointed in the service I received at PnP Cleary Park, Port Elizabeth. On the 12/04/2019 @ 12:47 I went to a till and asked the packer can I come through,she then says and I quote "No" which I politely left without arguing .As I went to the other till the cashier arrived,which I was then already at the next till. I paid for my goods via cheque card and requested from Ayanda(the cashier) for cashback as the mall is not safe for drawing cash at ATMs and its free at the till. She then says and I quote "I just arrived recently,you can ask the lady a few tills away as she was there for a while" I then politely said thank you and went to the other young lady at the till. As I approached there, I saw she cleared her til with one hundred and two hundred bills and put it in the blue cash up back,but theres no security or she didnt say she was cashing up as there were other customers at her till. I acknowledged her and asked politely if I could get a small amount of cashback. She looks at me and says and I quote "who sent you and told you to come here" and advised her it was Ayanda. So she looks at me,Ayanda looks at me,not knowing what to do and then I got upset as its not the first its happened to me at the same store. I've been going to PnP for more than 15yrs and today I just had it and to top it off there was no manager(the person with the red suit). When will the store realise that there are customers purchasing goods and paying for a service but nothing is given? I'm bitterly upset!!!!
