For Playtest Cloud, I just completed a survey, can the survey-maker deny my payment?

For example Dscout got those express missions where you qualify and immediately do the survey, then get money immediately. However, for Playtest, I did a long survey filled with like 30 questions, and in the end it just said they'll get back to me.

... What? So they have to be satisfy with my responses? I don't see anything else in there confirming I got the payment.
