I have ordered an black hoodie order no:cyn281769 and i have paid for that via online payment. But i gave the wrong size so i cancelled my order one hour after ordering through mail. But i didnt got any refund and i tried to call the customer care service... They didnt attend my call. So please kindly help me to get my money back in any form or atleast tell them to deliver my product.
