Under cooked chicken

Firstly I love the KFC fast food chain, so I'm disappointed that they couldn't handle a simple complaint which has *****ed my perception about the brand. I called the national number to report having being served an undercooked piece of chicken at the Blackheath KFC. I was told a customer care representative would call me, and I received an sms to confirm. I was advised to keep the piece of chicken in the fridge in the interim, which I did. That piece of chicken has been in the fridge for three days now, the only time I spoke to a KFC representative was when I called to follow up, and I was someone will call me. I've since spoken to Mpilo and Mbali, and I mentioned on my last call that if this is not resolved I would to complain through a third party. My complaint ref: cas-140908-x6f1j8.
