I am very surprised that this happens, not that I don’t believe you. I’ve ordered standard pieces and my SA didn’t even need to tell me that it’s not returnable. It always was returnable for credit. I thought VCA policy was enforced consistently throughout the country if not world. That is a shame some places don’t allow a return for credit. Seems pretty unfair. Are we sure that it’s not an SA not providing correct information to a less informed client?When I placed an order for Guilloche YG earrings, I was also informed by my SA that there are going to be no returns or exchanges since the order is being placed for me. I don't think it's that unusual. The idea behind placing an order rather than picking up a product readily available in the store, is that it has come specifically for you and in those cases the assumption is that you really wanted the item enough to want to order it without even having tried on.
My suggestion would be that you contact your SA and request a credit note. I don't think getting in touch with customer service will help as the online boutique and store boutiques for VCA are seperate entities that operate differently. Even their stocks are different! So is there exchange and refund policy.
