The Postal Service placed that sticker on the package, made the notations, and then placed it in the body bag. Most Postal facilities do not heat seal so taping them is common practice. I do not have all of the facts but you stated it was "cut" but in the photos it appears to be torn as a cut would be a straight line. Your local office would be useless. They probably place the and marked the damaged label then put it in the damaged bag. As far as they are concerned they did their job. I do not understand the "?" on the damaged label next to received without contents. If an invoice was inside that may explain it. I'm not making excuses for them but I'm trying to give you an idea of what may have occurred. My best advice would be to talk to and show the package to your mail carrier. They maybe able to give you more information about this package. Since a tracking number is present and readable I would call your local district office and report the damage and loss. Please, do not make any accusations as I know how Postal employees think. Calling 1-800-ask-usps will only send it to the local office. What you need is the district office. I have been very successful in having my district find the owner of items lost, presumably stolen, when it was damaged and is in the processing plant. Best wishes and glad to hear the seller and you were able to find a way to work together on this unfortunate problem.
