Not transparent

I purchased 2 items last week from 1 of your newly opened stores Renegade Fashion Outlet in Kuilsriver. Before i gave the items to the cashier I specifically asked “can I exchange these for a different size” in which the cashier rep**** yes. I bought a jacket and when I tried to return it today for a bigger size in a different colour , they told me they can’t except it because the barcode is different and their AM said no exchanges are allowed during Covid. Now I get the Covid part, but then why tell me I can come exchange when I can’t. Also why not MENTION the fact that he barcode needs to be the same. Also on each receipt that I have, it says “turn over for terms and conditions”... there is nothing printed.. completely blank! On all receipts!! So maybe if it was printed then I wouldn’t be feeling irritated by the miscommunication I received and maybe the fact that neither shop assistants bothered to apologize contributed to this review.
