Simply "disgusting" Chicken

Last night (09/12/2021), we decided to have rainbow chicken, simply chicken steaklets. To our shock and horror the meat was off and there was a green piece of chicken. I have tried contacting them on Facebook and they just don't seem to care. I've got pictures of the "chicken" and sadly before realizing the food was off, ate some of it which made me ill. This is disgusting!
