I wonder how much of "Item Not Received" is due to poor transport security, like delivering the item to someone's 'property' but just leaving it outside, unattended and unsecured.

That's part of it. The chargeback system is a complete joke, however. I had one guy that I was very suspicious about, so I hired a PI to see if the item was visible in his small business, and take a picture.

The tracking number showed the item delivered to the person, signed for with an known employee's name. I submitted this, as well as a picture of the item in the guy's shop. I still lost the chargeback. Got my revenge in the end though...see below.

A tip for anyone that's has a particular chargeback where they know they were screwed. If the issuing bank has any presence in your state...sue the cardholder's bank (or perhaps Visa/MC/AMEX) in small claims. In my case, Chase settled for the amount I sued for, which I made sure was on the high side. They don't like to spend money on corporate lawyers going to small claims.

First off, what a jerk, glad you got your money back. Second though, too bad you can't sue for damages in time wasted stressing out about this and having to file a lawsuit + likely do some research. Hopefully it was at least a few grand to make it worth your time. Hopefully also you appealed the first chargeback decision, which I'm guessing took at least a month or two.

Some people just seemingly think of creative ways to screw other people for fun, or because they figure no one will stop them.

Well, in most small claims court cases they can't send a lawyer, and have to send an employee who is unfamiliar with the case, which for a company like Chase may mean flying in an employee and putting them up for a night or two.
