True story that happened to me few weeks back. Our company is a subscription based company where we charge active users periodically. I've used an un-tested feature from one of our system which causes massive reactivation of users that have already unsubscribed. This leads to severe overcharging issue of already unsubscribed users to which till now I'm still cleaning up the mess. :-(
