Please see the file attached about the complaint, our agent checked with the restaurant that cockroach didn't come from their restaurant as the new plastic bags was always totally flat and there was nothing in there when they take it. It comes to the question that how often do we clean up the delivery boxes? Do you think that possible the cockroach might be hiding somewhere in there? Somehow we have to make sure that our delivery boxes are hygiene and be cleaning up daily as we dealing with the foods.
