I've been a Prime member for at least 2 years now. Within the last 9 months I've had numerous small ticket items not being delivered to my work address (I even put in the delivery instructions that our plant is open 24/7) even though the tracking shows that the item was dropped off in the front office or mail room. This only happens when the package was being delivered by what I'm assuming a 3rd party carrier, not UPS or USPS. Case in point: I ordered a 120mm USB case fan ($12.99) last Tuesday (4/24) and it was suppose to arrive on 4/27. Tracking shows that delivery was attempted at 3:55PM but the business was closed. I checked our security cameras (we have 10 HD PTZ in our plant) and nobody pulled up to our front gate, and I checked an hour before and after said delivery was attempted. On Monday 4/30 tracking showed that the package was delivered at 1:55PM, again, nobody but employees went though the gates, and I checked the cameras to make sure. I called Amazon customer service, explained the situation, and I get some spiel about how the tracking doesn't always reflect the 'real time' progress of the package whereabouts. I'm like,"What The Frak"? That's the whole point of tracking isn't it? And if the tracking shows that the package was dropped off but the front desk person and the security cameras say otherwise, what is going on? The Amazon customer service agent refunded my order, but I'm still a little peeved over this. I'd cancel Prime in a second, but my wife loves that friggin Alexa/Echo too much. Ok, rant off...
