I have looked up inventory for a certain Behavior and certain Geo zone. It says there is PLENTY of inventory there yet you are under delivering my ads. I would like to know what the issue is. I was told there was a glitch at one point and it would be fixed. Then It was due to updates and would be fixed. Then once again a glitch. Last I was told that those numbers are just estimates and you can't be held responsible for them. Well, those estimates are somewhere around 90% off of what I am getting, which if you ask me is an entirely faulty system. I need to get this fixed ASAP. It has been going on for far to long.
On a good note you are doing pretty well on all of my other campaigns and I appreciate that. You also give credit for ads that under deliver. On a bad note, You are not giving a full credit on the inventory you are under delivering on. Which I find wrong.
