KFC's inability to respond to complaints and extremely rude staff.

I made a complaint to KFC on tuesday due to one of their branches and their stuff who was so rude and humiliating to my mother and I. I wrote to the customer service email, I wrote to them on Twitter and Facebook and still absolutely no answer. They simply don't care about the customers. We are clearly just numbers to them. I am so disappointed as not one of their representatives took even one minute to listen what has happened. I would not suggest anybody to support a business who has no heart to even listen to their customers when something has gone wrong.
