You must of gone to the wrong sites. The ones im working with are 100% Real. They are large companies that have millions of users.... which is why their support isnt as good. I know a few friends that have gotten stuff from them. You just have to be careful with fraud. They will get u there. So just sign up with ur real email the first time.
my current site is :
http://freemacbookpro.com/index.php?referral=640036which is for a macbook pro. The highest configured one too!!! I just did the stamp offer and i just cancel it once it shows up on the site, and walla.... its free!!!!
