I had an interesting experience with UPS. My brother bought a gift for me for my birthday on Amazon.com. It was shipped to me from them, via UPS. My brother called me on my birthday to wish my happy birthday and see if I received his gift. I said I hadn't and he said his tracking info said it was delivered earlier that afternoon. That wasn't true because my wife was home all day. Our only thought was they delivered it to one of our neighbors.
So I called UPS and asked them what was going on. They said in order to figure out what happened, they'd have to put a trace on it, which has to be initiated through amazon. I asked if I could speak with the driver, because a 5 min conversation with him would let me know what house he left it at, considering I know the neighborhood. They refused to let me do that, and insisted their tracing would figure it out in 10-14 business days.
So I called my brother and he initiated the trace with amazon. I called several neighbors and none of them had it. The next day, a neighbor 6 houses down from us (address ended in 22 instead of 10) brought it to us an said UPS delivered it there on accident.
So a couple days later we got a call from UPS saying they completed their trace and they are confident it was delivered to the correct house. So I told the guy they delivered it my neighbor SIX houses down from us with the address not close to the same, and they said "oh so you have the package so everything is fine then?" I told them no, that their drivers are incompetent, and all they do is deliver packages yet they can't even do that right.
It was the fourth time in the last 6 months UPS has delivered a package that should have come to my house to the wrong house. Each time, they delivered it to a different house.
