It should be "kekkou." いいえ、結構です = No, thank you. That was a bad copy and paste. :sorry:
I showed it as an example because I thought it was easy for beginners. Personally I would use something with "iie" only on a person that was extremely pushy.
(Sore wa) Kekkou desu. Oh, that's OK....is better for refusing in a store.
