PanelPlace is not a Survey Panel so we do not send out surveys, the surveys you completed were from the Survey Panels that you have joined. If you’ve completed the surveys, the Survey Panel will credit the rewards to your account with the Survey Panel. How long does it take for the rewards to be deposited into your account subject to the process of each Survey Panel, which you may check with the specific Survey Panel.
Meanwhile, you could also login to your account with the Survey Panel to check on your accumulated rewards. Rewards usually can only be redeemed once it reaches the minimum withdrawal threshold set by the Survey Panel.
