Currently, I'm using version Zen Cart 1.3.8a and Database Patch Level: 1.3.8. Now, one of the areas that I'd like to improve is to provide a self-service area for customers to order and cancel orders.

For example, a customer order the wrong number of items or the wrong product, it would be a good idea to give the customer an opportunity to cancel the order(s).

is there a module that will meet this requirement?

Thanks
