I completed 3 surveys from them in a row, none of which credited. The first one took all of my answers, right through to the final demographics, & then told me they already had enough responses, so I received nothing. The second survey redirected to a blank page after I submitted my last answer, so again, I received nothing. The third one said I completed it, but my points never showed up. I'm done with them, as they're a complete waste of time.
