The Magento 2 Cancel Order By Customer extension lets your customers cancel pending orders by logging into their accounts.



This order cancel extension for Magento 2 adds the Cancel Order link to the dashboard and the order details page.

The order has been canceled because the customer changed their mind. A new order for the same item can be created if you still want it. 

A store owner can customize what message is sent to customers when they cancel or change an order.
