Checkers Parkview Fish contamination

Checkers Parkview closed their fish kitchen and counter. The fish is at the deli section with the other food and it is crossed contaminated. I bought a chicken may sandwich and went into anaphylactic shock and nearly died because the kitchen is contaminated with fish. I locked a call at head office and no feedbacks was given. Two weeks later i bought a beef burger for someone else and i went into anaphylactic shock again from just touching the container. The fish is still with the rest of the food at the deli even after i went to then and talk to them. This is a huge health liability as fish allergy is as deadly as nuts.
