We do not offer refunds. Once your deposit is placed in your account we pay our affiliates and when a prospect clicks or taps on your key word/s, the bid amount is automatically deducted from your account so the funds must be there in your account to cover these expenses. You may log into your advertiser account anytime and ad to your account balance and or select other or more key words and if you are promoting an app just ad "app" after any key words associated with your app and your prospects will be shown your ad copy for your app
