Green light for hours today, completed one - message from the survey said "thank you for completing this survey". clicked and ended up with:

Sorry
You did not qualify for this survey

not doing any of these anymore, this happens way too often. Same thing with Survey Surfing; last 3 I completed and got sorry you do not qualify.

all this year, way too many survey companies taking our completed surveys and not paying us. They continue to get away with this. unethical business practice.
