Ernakulam, Kerala, 682018

Hi my name is laizlo i am from cochin ernakulam today i went to center square mall mg road in 5 th floor there is kfc outlet.
I go thr and ordered 349/- bucket and i got the bill. The next thing i used to do is always do the survey and get the benefit. But this tym when i checked bill they didn’t fully mention the code below so i asked abt it. They said some answers and i dont get the point. I asked her i need do the survey. Then she took a pen and write the code and given. I told her this not fair. Pls do the need full.
