According to Silverman (2011) and Hsiao & Tang , (2015) questionnaire is the best means by which such a large population of customers from different parts of the world could be contacted within the shortest possible time. The questionnaire is advantageous because it can be administered through the telephone and other mail systems in instances where the respondents are not readily available to fill the questionnaire. This happened in the case of three respondents who were not available and had the questionnaires administered to them through email (Ziman, 2000;Saunders, et al, 2009).The questionnaire is also useful in the sense that the same questions can be collected from different respondents and that means that the responses can be compared to identify potential differences and similarities between different people such as gender, age range, professional background, family background, social class and location of the respondents (Silverman, 2011). Another reason why a questionnaire was used was also because of the ability to do effective statistical analysis. The statistical analysis helped to make more generalised conclusions of the research where necessary. There are, however limitations with the use of the questionnaire as a data collection instrument. For example, according to Creswell (2003) most of the information collected from questionnaire is based on the views of the respondents. They choose to say what they want to say and these may sometimes be false. Where false statements are collected, the findings of the research may be affected in one way or the
