Lack of customer service

I bought an item to be delivered through Pargo at Edgar’s Beacon Bay. The lady working at the tills by Pargo starts taking 2 people who were behind me to help without my consent maybe because she saw I had no items. Thereafter when I complained she had the nerve to ask her if she could take another 2 customers to assist before looking for my parcel. I told her “no” as I have other things to do than stand at a que at Edgar’s. She then says to me, all you needed to say was no. She barely looked at the cupboard behind her and then says no it’s no here with a stinking attitude and with no willingness to assist. Beacon Bay Edgar’s is actually closest to me and was even thinking of opening an account for my kids but after the service I received there I will never set foot there again. Customer service is lacking at that store - cashiers don’t even have name tags to identify them.
