Bad service, no feedback

Friday I called to order food. A man by the name of Oliver took my order and also confirmed prices that I had read out. When I came to collect my order the prices were different and order was messy and incorrect. Oliver did not show any remorse as his apology was not real. When I returned to work as expect I got into trouble for taking long as I had to wait for my order to be corrected. Opened my food and burgers were wrong and no cool drink in my bag. Chicken wings that my colleague ate were so old. Pictures were taken of the bones she couldn't even eat the chicken off the bone . I called Oliver very dissapointed and demanded that he delivers 2 free CORRECT burgers which eventually only arrived when I had left work. I also called regional manager, Max, and was almost in tears because of the trouble I got into and the bad service. He assured me that the store manager, idries would call me. To date no call has been received. I am appalled at the service I received and the manner in which I was handled. The fact that no attempt has been made to call me back and offer me some sought of solution is just shocking. Food and service was of a bad quality so I want my money back.
