The steps to cancel an order are as follows-

  1. Go to 'Orders'

  2. Select the order that you want to cancel

  3. Click on 'Cancel'

  4. Select your reason for cancelling the order (you can add additional comments if you want)

  5. Click on 'CANCEL PRODUCT'

Your order will be cancelled successfully.  

But if it has been dispatched then the order can not be cancelled.  In such a case, you can deny your order at the time of delivery.
