I once ordered a new pair of Jeans, expensive ones because I wanted them to last, from Amazon and got an obviously used and ripped pair sent to me.
I sent it back, noted that in my reason for sending it back only to receive an email from them with the same sentiment as you got. Luckily I kept all the receipts (figuratively) and took a lot of photos and screenshots.
Reaching out to support they apologized profusely to me but still it left a very bad taste in my mouth and I'm sure it'll happen again sometime in the future.
