Partial refund of AR down payments

Question

I did an AR down Payment for a sales order then AR invoice got generated and applied part of the down payment to that invoice. Now there is some unapplied amount left which I need to refund back to the customer and clear my unapplied deposit amount. 
Seems I cannot find a way to do that any suggestions?
Thank You
