Suffered the consequences for my complaint

Yesterday I went to KFC for a burger. When I got it, there was no fillet on. Only what must have been a CRISPY STRIP they use for twisters. I asked them to replace it with a proper fillet please. I do not pay half price for the burger so don't want a half a fillet. <br> This upset the cashier who went to the back to ask for replacement. When she returned, a few ladies came with her to look at me and went back. At the back they gossiped about me very loudly (I know because they kept looking and pointing while speaking, not very discreet) but I didn't understand the language. <br> Eventually someone threw a burger in the warmer so I left. When I got to work I saw ALL the lettuce on the burger was soft and brown and no tomato. I then broke a piece of the fillet and it was so DRY & HARD I could throw someone unconscious with it. <br> I called the store immediately. But they laughed, pretended the couldn't hear me then kept dropping the call. Im ****sed. Is this what they do to customers food who complain about portion sizes and service? I don't want to go to another branch, I want this staff to start doing their jobs PROPERLY, get an ATTITUDE ADJUSTMENTand I want my burger replaced.
