Net-A-Porter has the worst customer service of any designer retailer. After buying a pair of YSL Paige platforms $1200 USD, the strap came apart from the shoe after one wear, clearly a defect. I then repurchased the exact same pair from Net-A-Porter and they wouldn't refund me for the first damaged pair. Takes 40 mins to talk to customer service and they don't reply to email. I called three times to resolve the same issue, a total of 120 minutes on hold and just now they have emailed me back saying they can't refund me.
