Remember my old thread about a random refund from FACEBOOK ? Well just got this email " Hi, There was an issue that impacted some of your boosted posts from 1/31/14 and 2/5/14 and they may not have reached your intended audience. The issue has been fixed and you'll receive a refund that will show on your payment method in the next few days. We're sorry for any inconvenience this may have caused. Thanks, The Facebook Ads Team "
