I had this happen last night. 20 minute survey, 128 points. I completed it and it says it was completed, but no points. Usually I keep track of the survey #'s, but for some reason I lost track last night and didn't know which one it was. Wasted over 20 mins for nothing!
Today's surveys are a joke. I click on the red button and it just takes me back to the survey page. I've clicked over 50 so far today, and not even 1 dq point!
ETA: I swear I can never get my points credited immediatly, for Hallmark! I spent $12 in the store this morning, and when I uploaded the receipt I get the response "Insufficient Quantity." Now it's under review. (It's only requires a $10 purchase).
