I guess the portal that powers ads is to blame. They should set the right procedure for handling them. If they used the software like
https://astrad.io/user-acquisition/ that helps automate ad placements online, they would have probably saved a lot of money. Like it was with me, when I started my own project and didn't follow up on ads. It was a disaster in the beginning. But when I found a proper tool to control and automate things, my losses stopped. But I really sympathize with you. I think you should not waste your time on these small matters. Try to do the same thing that I did, I am sure it will help you.
