Asher Jumpsuit

I ordered this jumpsuit in a size small. Instead I was sent some extra small velvet pants. I tried to call customer service and the phone number doesn't work. I tried 2 different customer service numbers and both were non working. I sent an email to customer service and the email came back as non deliverable. No information on line about this problem. Other than you can spend your own money to return an item with an item number that is not even included on the invoice. What about my original order?
