Was right with the poster until the ignorant cop comment.
In any case the K's guy handled it terribly. The seller has full responsibility for any lost shipments (because he paid for the shipment and insurance) and should have refunded him in full when it was certain it was lost. The responses by the seller and lies they spouted back to the buyer are atrocious, what a terrible person.
I had a similar experience with a dishwasher part I ordered. 2 months later the tracking still said the same thing...it was obviously lost. I contacted the seller and explained the issue. They verified and promptly sent me another shipment, advising me to refuse the original one if it should ever arrive. a week later I received the second shipment and was happy. Another week or two later I also received the original shipment. I did as asked and refused that one and off it went back to the seller.
THAT is how any seller should handle these issues. Anything less and you are a terrible seller.
