I’m going through something similar right now. I ordered from Dior online for overnight shipping. Got a message that my order shipped but no tracking number. When I called they gave me a run around for several days and opened on investigation. I asked them to just ship me a new item since it wasn’t my fault that they lost it. They said they needed to do an investigation. So several days later I said it just wanted a refund. Now I got a message that it was an IT error and they can’t give a refund until they fix the IT issue. I think I will need to have the payment reversed by my credit card. Dior is not following through with shipping or giving me more information as promised. Super disappointed. They never even shipped it and I’m not getting a refund.
