They are quite certainly not monitoring their servers closely, I once had a application running on a small instance costing me more than 30,000$ in just a few weeks because it was doing expensive API calls to AWS. When a growth from <10$ per month to 30,000$ in about 2 weeks isn't concerning them why would 3000$?
