Be Careful With UPS!

Not sure what is going on with UPS, but I bought a used Rotel tuner off of e-bay (1st mistake) last week and it was scheduled for a Friday delivery. I was at home when the UPS truck pulled into my driveway at 6:00 PM. I went outside to meet the driver halfway and could hear him rummaging around in the back of the truck. He emerged finally and said he did not have my package. I went back inside and a few minutes later, I received an email from UPS saying that the delivery had been rescheduled for Monday morning. At 10:30 AM on Monday, I got an email from ebay, saying that my package had been delivered. It had not, and after around two hours of trying to penetrate UPS horribly bad customer service database, found out that someone named Hernandez had signed for the package. I don't know who that is, or where the package was actually delivered to. Plus, no signature was required for my package to begin with. Anyone else out there had a similar experience with UPS?
