Hello, you had a survey that you completed that was reversed. We don't know the exact reason why it was reversed but unfortunately that's the information we received from the research company. They did not accept your survey and as a result we are not able to credit you for it.
Reversals usually happen after their manual verification deems a survey invalid for quality reasons. They may also disqualify you for security reasons so make sure that you take your time to read each question and time to respond to them. If you RUSH through a survey or if you fail QUALITY questions or if you are caught as a STRAIGHT LINER you will not be compensated for the survey (even if you might see the congratulations screen) and your answers will be invalidated.
Quindi trattasi di un sondaggio Cint. Non dicono data nè motivo....piuttosto discutibile!
I tuoi 10 centesimi sono sicuramente di commissioni di un ref che ha fatto questo sondaggio.
Scusate ma chi altro è che gli hanno tolto 1 dollaro?
