Hi Sandman,
In some cases it will take a bit of time to receive credits from
your completion of surveys or offers, but if you believe an inordinate
amount of time has passed and you still have not received your credits,
please fill out a support request from the offer status page here http://www.wgt.com/user/offers.aspx. This will send a request to our partners at TrialPay who process the offers and who should be able to help.
