How IRBM take up customer rejection? Any action impose to Supplier?

As stated in Section 2.3.6 of the e-Invoice Guideline published by IRBM on 28/10/2023, the Buyer may request a rejection within 72 hours from the validation date of an e-Invoice with reason, however, it is subject to the acceptance of the Supplier. If the Supplier did not accept the request for rejection initiated by the Buyer (or did not proceed to cancel the said e-Invoice), no cancellation would be allowed after the 72 hours have elapsed. Any amendment thereon would require a new e-Invoice (e.g., Credit Note, Debit Note, or Refund Note e-Invoice) to be issued.
