Owner denies that fly eggs were present on sushi!

It took almost an hour and a half for our sushi to be delivered to our table. That was OK because we knew that it was quite busy due to all the people there. As i Began to eat the sushi i noticed an unmistakable group of fly eggs on the salmon of the sushi. I then notified the head waiter he then said he will let the owner know. After some time he came back to me and told me that the owner removed the eggs and put them onto a piece of paper but they did not move so they could not be eggs. I paid the bill and left without any apology or recourse just that the sushi which i instructed rpthe waiter to remove from the bill was taken off. I find that as a business owner my self this kind of treatment and the way the OWNER handled the matter is despicable. In the past 2 days i spent R2000 there. It is with great sadness that i have to resort to Hello peter to view my concerns but the owner was to arrogant to even come to my table to even assure me that the fresh plate of sushi was on its way.... A result that i would be glad to accept.... Ignorance and arrogance is obviously a better option. It cant be too hygenic eating at a place where the owner doesnt even know what fly eggs look like
