Refund /exchange policy

I've bought a cap last Saturday and I felt like exchanging it for a brighter color or get a refund.ive called the nearest store today to check which colors do they have on stock,only to be told that they do not refund or exchange accessories and it's their policy. However when I checked my docket the policy stated at tje back of it doesn't say anything about caps but it has a list of items that can't be exchanged or refunded due ro hygienic reasons and caps are not one of them. My cap has never bean worn and the tags are still intact. I'm not happy Regards Tebogo
