False Advertising

I have trying to order online as I saw they had nice bargain, first it kept on giving me an error message, I eventually got in to order then it said it delivers at my address between 11am and 8PM and I was ordering at 13:50. I went out of the app got in again they have removed the bucket for 9 and now I can order online in the stores that they said 5 minutes ago don't order online. Why must we get false adverti*****t I have been ordering from KFC online almost every week now that they have a bargain we are treated badly. This is not right.
