“animal interference”

I’ve had three separate packages delayed or just not delivered over the past month or two, all labeled as “could not deliver due to interference by an animal” — but I know for a fact that there is no animal interference, and they didn’t attempt to deliver them at all. I submitted a complaint about the very first one because I needed it for a trip and it was delivered the next day, but decided not to about the second one and it still hasn’t been delivered. I’ve actually always loved USPS and favored them over other carriers until I moved to my current address. I have heard from carriers that they don’t like delivering to my street. I’m so fed up and now I feel like I have to worry about retaliation.
