Hi Marshalaw,

Please click the link above and look in the top right hand corner for the Contact Support link. This will list the offers that have been viewed or are in progress. Find the Netflix offer and look under the Actions column. If 30 minutes have passed since you filled out the offer you'll be able to click the Contact Support link in the actions column. Fill out all of the necessary information and they will attempt to manually verify your information.
Most offers are completed rather quickly, but there can be a delay if your information cannot be automatically verified and unfortunately, that does happen once in a while.
