Hi Mog,
must be frustrating. However, I think it is not unusual that response rates for these kind of surveys is low, for which there are all kind of reasons: Overflow of requests for potential participants, questionnaire too long? Perhaps not appealing enough? Not knowing the person who does the research? Other priorities of potential participants (exams, X-mas presents)? etc. etc.
As such it may be useful to ask a few fellow students to fill in your questionnaire and ask for their honest opinion. Also, as mentioned before, if you would have access to key players, who can promote the survey, this would be a great help. Finally, think about the timing of the survey; I think December and January are probably not the best months to do something like this.:-)
