I had the same thing happen.......I went to where the tracker said the UPS truck was and luckily was able to get my package.I've had many recent UPS delivers where the "goal posts" were being moved mid-day as to delivery time. When that occurs, and you've stayed home to sign for an in-person only delivery it is frustrating. Last week I was waiting for a bass delivery, had the tracker working just fine showing a delivery by 3pm. Was able to watch it buzz all around my street for hours, only to have it update to delivery by 7pm right at 2:59 on the clock..lol
