Hi Chanakarn,
Did you checked portal correctly?
We replied promise date 24/MAR. Impossible our shipment to ship on 24/MAR and dock your store on 24/MAR right?
This is not local delivery. This is towards your appointed forwarder (From singapore) with booking of flight(To Thailand) for your shipment to meet 24/MAR.
Please check with your senior/next escalation for further clarification and understanding of difference for Schedule and promise date replied by supplier/vendor. Thanks.
