Verification on Git-r-free sites....?

I emailed support and the process was quite confusing. I need my 2 refs to be verified so I can cash out. Can anyone please explain about the pin # and how to be verified? Thanks

Its pretty simple, a machine calls and gives you tells you 4-5 numbers. For example if it says 3456, all you do is on the git-r-free site is write 3456.. That's it. Its been a while since i got verified but its pretty easy, and good, since less scamming.
