Seriously?!?!

Last week I ordered the cutest dress online from Macy's. I was so excited to get it in the mail. That package was delivered last night and when I opened it up, to my surprise there was no dress. Instead I got a WHITE T-SHIRT. WTF Macys???? How does someone packing up a shipment confuse a blue/green dress for a white t-shirt?? I mean aren't they supposed to double check these things? So now I have to get in touch with Macy's (because there is no way I'm paying for shipping to return this), and straighten this out and get what I freaking ordered! Have you ever had a mix up like this when shopping online?
