얼마전 바코드스캐너를 샀는데 표기와는 다르게 작동이 않되는 부분이있어서 

유투브동영상을 찍어 판매자에게 문의를 해보니 이런대답이 왔습니다.

Hello  Kim
We are very sorry. The barcode scanner supports QR code that maybe it doesn't support the bar code you scanned, and this product description was written by our former salesman, we sincerely apologize to you. If you don't want it, you can return the product to us and we will give you a refund. Feel sorry again!
Best Regards,

이제품을 원하지 않는다면 되돌려보냈을때 환불해준다는 말같은데 

알리에서 환불을 해본적이 없어서 주소적힌 박스도 버려버렸는데 이거 참 어떻게 하면좋을까요?
