Update:
Cartier sent the bracelet back to us over a week ago. When we disputed this, they sent an email that made no sense (sounded like AI wrote it). We told Cartier we didn’t want the bracelet and didn’t even open their package a second time. They eventually responded that since AMEX reversed the charge, they’d send us a return label and put the bracelet back in their inventory. I’m guessing they are hoping to sell the bracelet again even though they said they were rejecting its quality? I still don’t feel 100% at ease that the whole debacle is behind us, but fingers crossed this is the end. I definitely will never buy online from Cartier again.
