Appalling customer service - no refund on a returned item

Absolutely Appalling customer service! I returned an item unopened to One Day Only over a month ago and I am still waiting to receive my refund. I have sent numerous emails following up on my refund and have not received a single response. I will NEVER order from One Day Only again. I fear I will not receive my refund at this rate. This is day light ****** at it's finest. How can you receive a returned item and not refund the purchaser? Their service is completely unprofessional. A warning to all future purchasers, do not order from One Day Only, they are ******** and *******!
