scorpion in my Sushi

On sunday the 13th of September my wife and I ordered sushi from Ocean Basket just after mid day,my order arrived just before 13H15 the sushi was divided into 3 different containers so therefore we refrigirated the unopened sushi container which we kept for later the evening,upon opening the last container that night and started eating from the container just to find a SCORPION trying to gets its way out from the back row of the sushi container,now imagine we never noticed that insect and we have a 3 month old Girl what if it made its way into the house or the rooms as small as what it was,I'm sure on a rough estimate its just shorter than a match stick,on monday we then appraoched the store at cresta mall and asked for the manager on Duty,he then asked us to explain the problem to him,after my wife and myself telling him what happened he turns around and tells us we are lying because that has never heard of that kind of new before from his store,so I will be taking this further because we never even got an appology from him as we felt more humiliated infront of other customers who had to hear about our problem,we were not even taken into the office knowing the problem we have!!!!!
