<human>: I think the post office lost a package I was returning to Amazon. I have never done a return and have mailed very few packages so I don't know what is normal. It was expected to arrive at amazon on the 22nd of August and as of today it still hasn't arrived. I "opened an investigation" after it didn't arrive after 5 days. Then Friday (after calling) according to tracking it suddenly showed up at the Lexington, KY post office (it was going to Lexington) then last Saturday morning the status was changed to "Sorting complete" it has been "Sorting Complete" ever since (8 days). I called back today and the woman couldn't tell me anything that the website couldn't except that my previous investigation had been closed... I asked her if there was someone else that I could talk to and she told me to call the Lexington Post Office. I got their number but it is all automated and I couldn't find any way to get to a real person. Now I am at a loss as to what to do next. Am I just being too impatient? Has anyone else had a similar situation, what did you do?
