This post is a warning about UPS in New York. I missed a UPS delivery 3 times, called the 1800 number and was told to pick it up at 522 Greenwich in downtown Manhattan. The pickup center could not find my package, and was staffed by rude and unmotivated personnel. They were also looking for the package by hand, without any type of computer help. The UPS call center has no connection with the pickup center, you have to call the pickup center itself to confirm that your package is there.
By setting up their central call center this way, UPS shows a blatant disregard for the worth of customer time. The disparity between the delivery logistics (which are quite good) and the end-point exception handling (absolutely terrible) is amazing.
