We've been having this problem with FedEx for some time now. A few months back my husband was sitting right next to the door because we were expecting a wine shipment (an adult has to be there to sign) when he heard a faint noise at the door.
It was the FedEx driver writing a note stating we were not at home. My husband asked him why he didn't ring the bell and the driver insisted he had but it wasn't working. My husband then rang the doorbell right in front of him to show him that it did indeed work. Then he asked the driver why he didn't knock if he thought the bell wasn't working.
The driver answered that people don't like them to knock, a pretty ridiculous answer. We called FedEx at that time and told them of the problem, but the same thing happened this morning. Once again, we were home waiting for the package but all we got was a slip on the door stating we weren't home.
Supposedly the driver is coming back tomorrow and supposedly he's been instructed to ring the doorbell and/or knock. Maybe I'm old fashioned, but I think if a company is telling its customers that they deliver to a person's home, then they ought to make a serious effort to do so, and that means letting people know you're there.
Reason of review: Problem with delivery.
Preferred solution: Let the company propose a solution.
