May 22nd, hacker’s used my map api key which is supposed to be public, and charged 35K in 3 hours. My monthly usage was 100$. Complete silence from google side. Billing chat keeps say give us 3-5 business day. I give them 3-5 business day every week since last 2 months. I lost my customers, lost my startup. Just praying this outrageous charges would go away. That’s all i can do at the moment. We are loyal customers to google but google treats us like we do not exists. I spent 1000s of dollars until this incident, and i was going to keep spending. But that is what i get in return.
