    “Good communication and trustworthy in terms of delivering work. Very polite. However, it feels the job was attempted without giving good attention to the questions and their exact requirements. This is reflected on the lack of quality of the overall work which will probably lose lots of marks if submitted like that. I had to consult other people to complete the job myself.”
