The WORST customer service EVER. Ordered a PAIR of sneakers for my daughter, paid for expediting shipping, received 1 shoe. Called and was told the other shoe would be sent via next day mail. 6 days later no shoe and no one can tell me where it is. Store managers refused to give me a tracking number to try and track it myself. Got the run around from customer service and the store managers. I was given a refund to "satisfy" me.
