Got a little problem:. I ordered something from Amazon. I track the package and I'm told an attempted delivery (usps) was made on July 23rd, but my driveway and front door were not accessible, and we'll try to deliver it again.

We can't think of anything on July 23rd that would render our driveway or front door inaccessible.

Amazon let's me return or exchange for a variety of reasons. They seem to have NOTHING for a package that has simply not been delivered.
Any suggestions?
