This has happened to me recently. Yes, it's frustrating when I spend half an hour trying to qualify for surveys, only to be told "sorry" after I think I've completed a survey. I just walk away from my computer, go do something completely different to take my mind off my frustration, then try another survey company later that day. I just have to remember that not every day will be a good survey day for me, but some days will be, and that is what makes it worth it!
