Why microwave a fish patty???

I chose the Mzansi Fish Burger on the 13th April. They started by placing the patty into the microwave. As a result the patty came out exceptionally hard on the one side. The patty was also tasteless and had it not been for the pink sauce it would have been a waste of money all together. I have tasted fish cakes that far supercedes this taste. Totally disappointed.
