Did not get what I paid for

I went to purchase a meal from KFC point road. I wanted streetwise pap meal. but was told that they are out of pap. Then I asked for a Zinger burger but was told they out of zinger fillet. They offered the regular colonel burger instead which I accepted. When I got home to eat my meal I was shocked at what they gave me. Inside the bun was a chicken fillet with some sauce. That was it! No lettuce, no tomato, no mayo...nothing. Just a bun with a fillet and sauce. This is not what I paid for. As it was late and I was hungry, I had to eat it. I have taken pictures of the burger and the receipt. What kind of business is this. This shows total lack of respect for the customer. No ethics and integrity whatsoever. I will never want to buy from this KFC ever again!
