Slow service and cold food

I visited the Kentucky (opposite the Woolworths in Malibongwe Drive) to buy breakfast today at 7.17. I had to wait more than a half an hour to get to the service area. The lady handling the intercom was rude and just wanted to take my order without giving me a chance to decide on my meal. When I eventually arrived at the pay point (which was also done at the delivery point, I enquired what the delay was and was informed that they have a shortage of staff. Still waiting for my meal and cappuccino, I insisted to talk to the manager. I told him of my experience and he apologised. He offered me something extra for the inconvenience and I asked for 2x chocolate krushers, he could not provide it because the machine was broken (which is the case for more than a month already). I then asked for an ice-cream, but the machine was again not functional. I then request 4x chicken wings, but he wanted me to wait for it for another period of time, which I was not willing to do. He then shuffed R10 in my hand, which I took, but consider as a bribe not to take action. Eventually when I left, the food, including the cappuccinos, was ice cold which I gave to a beggar. Please investigate
