KFC feels feathers for customers

On 2 Feb, we purchase zinger wings from the KFC Phoenix Plaza branch. To our surprise we found feathers still attached to the wings. I kept the offending products and emailed the customer care center, detailing my disappointment. I was contacted the very next day by a customer care rep who said that somebody would be in touch with me within 48 hours. Over a week later and follow up emails I am yet to be contacted by somebody. Clearly KFC does not value its customers or their opinions.
