Here’s what consumers have asked with answers from Dillard's staff and previous consumers.
There may be a few negative complaints but Dillard's is actually one of the highest rated retailers on this entire site! It pretty much has one of the best overall scores. And that's saying a lot for any retailer these days. I was surprised myself. If you've had issues, try to take a multi-pronged approach such as myself, calling, emailing, live chat (if they have it) - until you get a resolution. Also, try to find a feedback section and state your case there as well. Good Luck.
I don't know about their in-store customer service, but the phone representative I talked to was snippy. As far as their return policy, for online purchases, just be sure not to use PayPal because they won't refund it and don't tell you that when you order. You have to find out the hard way, when you get a "gift card" in the mail.
