Terrible service!

I just started working near Trade Route mall in Lenasia and decided to go to the Pick n pay for some lunch on arrival at 12( which is lunch time ) got to the kitchen where there was not any fried chips, so I had asked the employee there are there any chips available which the response I get is NO!, I then ask do you know how long it will take to prepare it, the response i got from her was i don't I then said it is okay i will come back . After a half an hour i returned and i asked another employee ( Priscilla) when will the chips be ready , she then walks away and i follow her to see her taking frozen chips from the refrigerator and then starts preparing (by putting it in the deep fryer ) and she then says it will take 5 minutes which she constantly kept me informed by acknowledging that i was waiting ), My issues is that the first employee had given me a response (WITH AN ATTITUDE!) that made me believe the chips are being prepared which was not the case and she also ignored my colleague and i when we returned and didn't bother to prepare the chips in the 30 minutes we were away . I AM ANNOYED !AND IRRITATED! , that my time was wasted and that I have to deal with a persons rudeness during my lunch break.
