The huge adCenter overcharging bug this past Friday was patched towards the end of the day Friday. Microsoft promised to refund all the overcharging that occurred throughout the day in their blog post.
I have actually received a refund for this already. It was automatic and happend sometime on Sunday. Support also just phoned me to say everything was sorted and back to normal, but those who still have the paused campaign problem should be fixed asap. Didn't affect me so didn't ask anything more about that.
I have to say that adcenter seemed to do a good job at fixing what seemed to me like a massive problem, and fixed it quite quickly.
Yeah my account averages like $40/day and then I log on a couple of days ago and it is at like $350.
This was realtime via a report so I couldnt see why it spiked but I figured it was just adcenter trying to hit my monthly budget (which they were not even getting me close to it) but then I logged in today to look over my account and it now shows like $61 for that day.
I guess they fixed it without notification. Im happy about that!
People still want to know why this happened in the first place.
