Bad attitude from the store manager Sibusiso - Consumer Complaint for PEP STORES

I visited your PEP store in Jhb Bree Simmons Street this morning 19/10/2020 around past nine (9) and I received a horrible service from the store manager his name is Sibusiso, I was in your store to come and exchange items I bought yesterday 18/10/2020 at Soshanguve Crossing due to incorrect size. As I entered the door there was a security and I advised him that I was there for exchange and he told me to stand in the line to be assisted, Which I did and I spoke to a cashier that advised me to leave the items with her and go to the floor to choose for another items, after getting what I wanted the store manager (Sibusiso) rudely instructed me to stand in the again so that I can be assisted. I told him that is time consuming for us customers and I cannot spend over 30 minutes in the store for exchange and He further told me that if I don't want to follow his rules then I should go shop somewhere and that the store doesn't need my money.
