Refusal of assistance for a delivery - Consumer Complaint for PEP STORES

Today I went to one of the stores to pick up a delivery, a guy named Aphelele at the Gugulethu Square Pep Cell refused to assist to assist with the package claiming that I had to have a pin, I showed him the text I had received from the delivery centre,he was speaking so loudly that I felt like he was thinking I was stupid, I told him repeatedly that the text sent is what I have used in the past to retrieve parcels,I had to leave the shop and try to call and ask about this pin he's requesting, I had to go to a different teller to assist with the details I had, and that was Vuyo who assisted me.
