Hi Pacman,
http://wgt.com/user/offers.aspx
Unfortunately WGT cannot provide support for the offers since they are handled through TrialPay. Click the link above to visit the offer section. At the top right you'll need to click on the Contact Support link. You should see the offer that you attempted to complete
there. Under the actions column you'll see a link to Contact Support
that will be active as long as enough time has elapsed. Please click
that link and fill out all of the requested information for any offers that were completed that you have not received credits for.
Please note that most automated requests are completed with 30
minutes, but can take up to 1 business day to fulfill, so if you just completed the offer I would
recommend waiting 24 hours before submitting a claim.
