robbing clients

I went to pedro in boksburg, boxer centre, cnt leeupoort street to buy 2 quarter chicken meal for me and my collegue for my lunch. when I got to the office, I realize that the was chips missing. I then called the store to inform them, they asked where I work and my office details and said they will bring it after 10 mins that was at 12. I am currently knocking off now and no one came. I had to eat my meal without chips that I paid for. this is robbing people, it is unacceptable at all. my order number was 15.
