What is the procedure to cancel the placed order?
You can cancel your orders until that have not entered in the shipping process. You can cancel your orders till they are in the processing mode. If an order entered in processed mode then you can not cancel it. To cancel an order, you have to login in your account, just click on the My Account link in the top right of any page on the site. My Account page will be open which shows the current status of your order, where you can click on the ‘Track Your Pending Orders’ link to view all the orders that have not yet been fulfilled. You can then click on the order number that you want to cancel and then finally click on the Cancel Your Order link available for that order.
