Ok empressmom. Thank you for letting me know. I have never seen a Voice Five or an Opinion Connect survey DQ me at the end of the survey. Not once. Not ever. Bad luck for sure!
In fact, Opinion Connect's final question is always 'how did this survey compare with others you have taken recently?' I reached that point. As far as I know, this means I successfully reached the end of the survey. I have never seen Opinion Connect surveys behave any other way.
