My DD had the same (or similar) survey this morning - they asked for a child to fill it out, so it might not be the same one. It went back to a white thank you page. I had one that went to a white page a few weeks ago and it never credited. I'll probably try to get one later since I think the one she did won't credit. I did report it as a problem, although I'm not sure it counts as a problem since there was a thank you and GF probably got its info from it.
