when you have completed the otx survey do you get the thank you page that says thank you, we appreciate your participation in this survey, we hope you'll continue to participate in future surveys as we value your opinion or do you get the thank you for your time and your willingness to share your opinion with us but unfortunately you did not meet the criteria to take a survey today. they do look the same as the both say thank you but only the first one will give you the credit you deserve. i know how frustrating this must be for you as it happened to me a lot in december (at least 10 or 12 surveys). the only thing i can suggest is to keep clearing out your cookies everyday and to keep trying - that's all i have done and sometimes it works and sometimes it doesn't. i know this probably doesn't solve your problem but i did want you to know that you are not the only person that experiences these problems and i have empathy for what you are going thru so keep smiling.
