floppy131: I was ripped off with zip reality free credits 450. I signed up and confirmed with the code and still no credits. What a Ripoff. They only wanted the email address so they can spam you.
These are not paid through WGT. They are done through TrialPay. You will need to contact support! To do so click get credits > earn free credits > in right hand corner there is contact support, find the offer you mentioned and follow the steps!
Sometimes they just need proof, as in an email confirmation.
Good luck,
