How to view an Expense Refund

Hello

I have a simple expense for $100 to vendor 'Shop Inc'  that's refunded a week later (categorized under 'Expense Refund'),

When I look at the vendor (menu: 'Sales/Vendors'), there's no mention of this refund. None of the reports seem to show it either. 

How would I ever know that money was refunded?

Thanks.
