Stupid PosExpress

I wonder whether is it because of the Raya Mood. Post office managed to lost a PosExpress mail from KL to PJ. I'm so upset by their service. They are simply too irresponsible. Why would I want to pay for the RM4 for the postage where they can lost your mail? I should have just mail the item via normal postage which is simply much more cheaper!! Argh... Super unhappy!!!
