I don’t know why they not contacted AR earlier. Invoice pending payment AR re-process billing on 8/9/16 by customer wrote date to payment for inform us that this invoice will be payment on 28/10/16 by this time, they don’t make sure can be give cheque on 28/10/16, they call to confirm payment again before 28/10/16. The reason why I BLOCK because customer can’t payment within 10 days after reprint document billing refer our meeting with Angie and you in A6.
