Joe's Crab Shack review: My problem about the food. Unclean shrimps and over cook fish

Hope this reach the right person. I was very excited to go to Joe's crab shack in Clifton New Jersey. I am a shrimp lover. I order the 1 pound of shrimp and the Pirate plater, instead replace the grill fish with blackened mahi-mahi. When I received my hot shrimp I was so happy then my smile turn into a frown. Why is the shrimps not clean? I was told that corporate change their policy. How nasty is that. I told the waiter to remove this from my bill. He kindly did. Now here comes my meal. Love blackened mahi-mahi start to eat it the fish is rub. It was over cook. I was so upset. My companion and I did not experience good tasting seafood from your company. The only thing he said was his crab legs was good. Mussels, clams had no taste. He stated my youngest child could had cook this better. I hope someone look into this matter. You do not want to lose customers. I am a foodie and I always give family and friends report on my experience on restaurants but I can not give a good recommendation on my experience at this time.
