Has Anybody Else Done the McDonald's Menu Concepts Surveys?

Has anyone here done the short surveys about McDonald's menu concepts? I've done 5+ and they always stiff me in the end and it's so frustrating. I don't speed though them and answer everything correctly, but then they're cheap jerks in the end and won't compensate my account after completion (it just gives me a DQ message, even though I completed the survey in full). I only keep doing them because they're short, in the hope that I've been compensated with the swb.
