I paid for guaranteed overnight delivery of four live koi fish from UPS. They were supposed to arrive today by noon to my home in New Orleans. UPS emailed me today to say that the fish will not arrive until tomorrow despite being in the New Orleans warehouse today. I called them and begged them to work with me because the fish will die if not delivered as guaranteed - they wont even allow me to go to the warehouse today to try to save them from running out of oxygen and dying tonight. I will never use their overnight services again.
