Registered cover from Germany

I received registered cover from Germany. This cover was opened by custom workers and ruined by this ugly yellow tape. Fortunately, they ruined only one stamp. They always open covers and parcels like neanderthals and put this tape with their legs. And then you must pay for customs, taxes and opening! What a theft!
