The take survey button (peanut labs always ?) seems to work just as expected. All the other's you need to add to the following to the time they take to complete:
1. Screen shots everything and especially start / end pages;
2. Contacting the sponsor about the scam with the above, and where and when completed.
Do all that and they will pay in my experience. Whether it's worth all that pain...up to whoever is doing it. Not good but how it is usually!
As said above it's not WGT. Apart from pulling them I can't see how WGT can police it properly either. Crapola but way it is...................
EDIT: Do chase the Sponsor on your one (looked again and not a survey). Hopefully you will get it, but proof of purchase will be needed. Good luck anyway.
