Maybe you thought the response was rude because they used capitals? But that, I think, was only because they wanted to get their point across that the survey qualifications/disqualifications are based on your individual demographics and such. Some, like me, just don't have the right demographics for any of these surveys. FC has nothing to do with this process. As for your statement, "They need to clean up their act or the site WILL fail," FC has been opened since June 2005...so if the site hasn't failed yet, I doubt it ever will.
I'm sorry to say this and I hate to be rude and flippant, but sometimes all you can really say is "that's just how it is." Life is rarely ever fair. I never get qualified for surveys either, so I just move on and quit doing them. There are other ways to make money on this site.
I read in the reply, that you rarely get credited for stuff? Might I suggest that maybe it's your browser. For me, IE works better than Chrome (i.e. I only can get the daily emails, PTC, and videos to credit on Chrome). I think FF is pretty good too. I would also follow swogden's advice and clear cookies and your cache, not just for surveys, but for all the offers. Possibly, you may have to disable your ad blocker too. That software blocks the company's tracking of your successful completion of offers.
