I'm obviously sorry that it's not working out for you but am also feeling vindicated that I haven't bothered with them for the very same reasons as you. All seem to be timewasters, etc.
Online surveys are hard to manage, take time to fill out, and often bring you nothing but more prying into your life.
There are some good ones out there, but the fact that they pay so little means that you are really wasting your time.
Like most money matters online, make them a small part of what you do, rather than a needless time swallower...
