Manufacturing defect
"I sent you an email three business days ago to inform you that one of the products I ordered has a very visible manufacturing defect (The zipper on the black sweater is way too long, so it’s uncomfortable and really not flattering when I tried it on), and I still haven’t received a response. However, the second item from my order is great — I have nothing negative to say about that one. I waited three days before writing my comment to ensure I was giving you a reasonable timeframe to respond, taking the time difference into account."
