I made the mistake of mailing my parents a package last year of Christmas presents for all of them out there, via USPS. Idiot me, I didn't insure it, didn't get tracking, etc. It got lost. I was heartbroken and kicking myself.
Likewise, my parents sent their Christmas package to us 2 years ago via FedEx. Dad went down to the local pack & ship place, and the gal said FedEx was the cheapest, would still get it to us before we went out of town to MIL's, etc. Well, FedEx didn't deliver the day they were supposed to, then an ice/snow storm came through. UPS managed to get deliveries made, but FedEx didn't. Mom & Dad had paid for gaurnteed delivery, which FedEx missed. Then the weather screwed them up. I was stightly understanding, until I saw UPS making successful deliveries. The whole thing was a mess, and FedEx wasn't trying very hard to deliver anything. Then they said it would be delivered, but by then, we were going to be out of town. I'm not sure who Mom & Dad called, or who they spoke with, but next thing I know, the Manager of the local FedEx was at our doorstep, with our package....oh, and a FedEx clip...like the ones you use for chips. I was impressed. LOL
The only foobar UPS has made was sending back a SU package this summer. A friend of mine was going to pick it up for me since the driver left one of their notes. She couldn't get out there, but I got in town right before the deadline. So I called their number. Customer service told me she would note in the computer to hold it for me, that I was going to pick it up the next day...which happened to be the day that they were going to be sending it back. So the next morning, as soon as I could, I lugged the kids down there to pick up my SU order. They sent it back! I was livid. The lady at the counter went and got the manager. I explained to the manager what the CS gal told me over the phone. Then I'm told by the manager that the CS person was basically out of line, and that's not their policy. I told her that their customer service needs to get their act together then. Thankfully, SU reshipped the package, with no extra charges. I was home when the driver dropped it off, and he asked if I had gotten my last package, the one he left the note for. Once I told him what happened, he felt so bad. He wasn't happy either because UPS "made [him] look bad". Since then, if we're not home when he brings a package, he leaves it in the back door and a note on the front door. Other than that, I've had great service through UPS.
