Trouble with exchanging an order

[sln]

I'm not sure if I have gone wrong somewhere but we had an order, the customer wanted to return 4 of the items in exchange for 3 new items. This leaves £12 owed to the customer. I created a return for the order and added the new items but it shows that I can refund the £79.99 and collect £58.99. I want to do this in one transaction of refunding £12 rather than two separate transactions. How do I do this?

I haven't found a completely smooth way of doing exchanges, but here is how I do it:

First I un-archive & un-fulfill the original order.  Then I click "Edit Order" and remove the items the customer is returning and add the ones they want in exchange. 

This allows me to bill or refund the difference in one transaction.

It works perfectly, except it does kind of mess with my reports.

Thank you, that has helped! I won't mark it as a solution as hopefully a way to do it which doesn't mess with reports will come up but that definitely works for the short term. Thanks again
