Really fed up with the number of surveys that screen out beyond the 100% point now. Latest culprit being a survey on investment platforms sponsored by Robinhood (survey sponsor is revealed at the end). Agreed to let them process my personal data when submitting the survey and then, wham, "sorry, we've ended the survey early".

Also noticed that (as per Happy's post above), eRewards are no longer giving the correct reward so easily after contacting them either. It seems to be such a common problem now that "Privacy" send an automated response asking for further info!
