I overnighted a passport for Next Day Air Early A.M., guaranteed delivery by 8:00 AM, to my partner, who had forgotten to bring it with him on a multi-city trip that included a flight to Canada. The passport was reported as delivered at 7:58 AM.
In reality, the passport did not arrive until 8:40 AM, and my partner had to scramble to make it to the airport on time. UPS denies any culpability, and it claims that there is no way that a driver can lie about the time of delivery. But apparently there is. The only proof we have is a call my partner placed to UPS customer service between 8:00 AM and 8:40 AM that day (4/25/12) asking the customer service representative when the passport was going to arrive.
However, UPS denies that any such call was made. Liars!
