Misleading

We ordered food from the newly opened mochachos in Parkrand.The food was delicious and fresh however I'm a bit annoyed.I was charged for extra sauce on the chicken and the cashier also confirmed that he is adding an additional fee for extra sauce , however when the chicken arrived there was no extra sauce,when we returned back we were told by the cashiers that if we want extra sauce we must again pay another fee.This is against the consumer protection act as the business cannot state on the till slip that they are charging for extra sauce and then refute that and ask me to pay extra.Thats very deceptive and misleading!!!
