Where is my refund? Order #*** Cancellation Notification

Terribly disappointed in Exclusive Books, had two great online purchase experience and now struggling with number 3. I place a large order on 25th Feb, and it has been marked as in warehouse since they took my money. I have sent two requests to Cancel. Went into EX Canal Walk only to have someone tell me that EB online is a sep business and they could not help me. MASSIVELY FRUSTRATED! Please confirm cancellation and refund = Order #*** Cancellation Notification, very simple especially if you are not able to provide the goods you have taken payment on.
