Bank reconciliation question

[David Goodenough]

A community association for which I am treasurer for recently had someone succeed in 
getting our bank to open a Direct Debit on our account without our authorisation.  
They took 4 payments before we noticed, and now the DD has been cancelled and the 
money refunded.  We use GnuCash to manage the association's money.

How do we reconcile this?  I know how to reconcile a pay transaction against an 
invoice, but here I need to reconcile four payments for which there are no invoices 
against one receipt.  We have already imported the OFX file with the four payments in 
it (which is when we noticed them), and will shortly import a subsequent one with the 
re-payment in it.

Thank you

David
