UPDATE: I've submitted the appeal. Their statement saying the letter would have required information for the appeal was a lie. I was able to state exactly what happened and was able to upload the image of the internal image of the two addresses that were mismatched at the fault of the postal worker. I'll update once I have more information.
Appeal denied on 11/24 with no reason whatsoever..... At this point, USPS is committing fraud by taking our money and automatically denying a legit claim (with evidence). I'm debating on taking the clerk & postmaster to small claims court, though it'd be very hard for me to deal with that due to work. Filing another appeal.
