KFC Worst experience ever!

I gave feedback on Monday based on my experience with this KFC and through communication advised that I would be contacted by customer service to discuss my experience or issues, the agent Amanda attempted to contact me towards the end of the day like just before 5 while I was in a meeting, I called back a few minutes later on the number she left and was advised they would get her to call me back, she never did even until now, I rep**** to the emails as well and still no contact, next step is Hello Peter to express my irritation and anger at the lack of efficient service from the store and now "customer care", my order was 25 minutes late and they sent pieces I specifically said I did not want, Customer care agent Amanda sends an email today saying my case is closed yet I have never spoken to her and she never called me back KFC Gatemax and on a whole sucks after this experience
