Poor customer service

My 3year old son was treated like a ***** just because he was wearing a jersey that we bought at pep two months ago ,they asked if he came wearing it then I said yes they watch the cctv if they don’t believe me and I didn’t know that we are not supposed to wear new clothes that we bought at pep when we come to shop with them , the most painful thing is when they start to touch him and looking at the back of the hoody the sniffing him to make sure the hoody smells like washing powder mind u my son doesn’t like talk or being touched by strangers yoh they ruined his whole moody for the rest of the day
