We are very much regret to say that your a/c has been so long outstanding. The reason is that we have had very heavy payments to meet lately and, at the same time, have been unable to collect many large accounts due to us.
In the circumstances, we should be much obliged if you would be so kind as to allow the a/c to stand over for two months that we would like to confirm date to payment as full payment of the outstanding AUD 35,044.33 within January 20, 2017.
