Disgusting Service

I'm so disgusted in the service. I ordered food from Nando's in parow on the Mr D app. Estimated delivery time for my food was 1:14 I decided to track the driver as it was nearing the time for my food to be delivered. I noticed the driver was way off track so I decided to msg him on the app chat. He ignored my msgs. The status on the app now said delivered. I called the restaurant and the manager on duty asked me to call Mr D. As I am about to do so he pitches up. Nearly 45mins later. I asked him where have u been. This driver looks at me as if he dnt understand what I'm saying and walks off. My colleague and I ran after him and he just gets on his bike and leave . I call the restaurant again and the same manager advises me to call Mr D. Long story short...I had to call every day for the past 4days.i am ignored by managers claiming they will call me back. They refunded me only 50 percent of my order and now no response from my online queries. Agent Tamlin promised me she will get back to me but did not. I am frustrated and will never advise anyone to order from Mr D unless u ordering cash on delivery. They hire drivers that can't even speak English or understand basic communication and then want to hold the customer responsible.
