Constantly..........sometimes we don't receive mail for a day or two. Once I was waiting on a package via USPS, tracking info stated that it was delivered. I go to the local PO and ask that they investigate. Was told by the clerk that tracking info states that the package was delivered to my address. I stated that not only did I not receive the package, there was no mail delivered that day and that I was home all day.
She stated, "Well maybe you went out." What? I said maybe it was delivered to the wrong address. She says, "Even if it was, it's considered a good delivery." I ask to speak with a supervisor who reiterated what the clerk said as it being a "good delivery."
Long story short, I spoke to the regular mail person who stated that she left early that day and that she would track it down for me. An hour later she shows up with the package and says, "Not only was it delivered on the wrong street, it was also the wrong hundred block."
