How do I reconcile the account

Hello AdamR8974, 

Welcome to the Community page, 

So have you received the money in the account? If yes then you need to record the money on the invoice for the amount you paid  then if you then send the over payment back you then need to  do an expense  and then link the expense to the  unapplied payment like a credit note and then  match bank, or you just do a refund receipt and pay the money back and then when paid correctly then match to the invoice. If you have  recorded the payment in then post it to creditors and then the expense out and link off and then when the money comes back in then link to the open invoice.
