No refund provided

I ordered clothing from spree and was sent a response email saying some of the clothing I ordered would not be delivered due to a stock issue at their warehouse. They said the would reimburse me wih either store credit or a refund. I have sent multiple emails over the past 2/3 weeks explaining that I would prefer a refund but none of my emails have been rep**** to. I even tried calling but it automatically sends you to a prerecorded voice over explaining details about the online store so you don't actually get to speak to any one.
