I need to return an item but someone hacked our acct so they terminated my debit card and are issuing a new one. Can I still return it and at least get a store credit?

First call the customer service and chat it helps

If you don't have your receipt go to your bank and get a print of your purchases.

Im sure by calling customer service and proof by email you should be able to

Proof of purchase. That's it.

On the tag they put a small sticker with a bar code, they can look up the transactions with that. I think they will give you a store credit card something like a gift card for the refund amount. Good luck!

All you need is proof of purchase.
