Had to send a claim to Trialpay for Toluna. Signed up and did a bunch of surveys, and now get e-mails from both Toluna and HTC, but no credits.
Toluna didn't send a confirmation e-mail after the "click to confirm" e-mail, but sent other e-mail after that, so I hope those are enough evidence.
Also had a couple of videos come up above the commercial carousel that offered 2 or 3 credits to view, got nothing.
And after being kicked from a couple of surveys under the Survey tab, got the rate your experience screen and the 5 credit consolation prize, but never got the credits.
