I can understand that they open it, maybe they did not pay enough attention, but why keep it there for so long. What they gain to do that? Make me wonder, how many times it happen with non tracking mail, and this kind of people keep/read your mail.
Agree, pretty sure a neighbor got it. We left the house that night around 7:00PM, so I don't think they delivered that mail a that time. Plus it says that was delivered at 2:04PM, and make sense. I check the delivery of the package the mail man left a the door, and it says that was delivered at 2:06PM.
I contact USPS via email, but they did not yet reply me.
I did not chose the shipping method, because I never had any issue before.
