Rotten/black dotted chicken

On Thursday 30th August I purchased 8 pieces of chicken with 3 sides at KFC mulbarton only to arrive home and found these black marks/spots on the chicken. My 3 year old child had a bite of the food and I hope that she'll be okay.

I am very disappointed in how the matter was handled, no apology was offered and I asked for a refund.

I think the staff needs proper training I thought of posting these pics on social media to warn others.
