We had a similar experience. The first notices from google said we would be below the free tier so no problems. Turns out we passed the free tier the first hours of the first day of the month. Needless to say we are moving away from all google services we have used, either setting up dedicated servers or paying some other company for the service. In the case of the maps it's much cheaper to pay for a dedicated server with 1 GBps bandwidth than to continue with google maps. And we can update the maps ourselves if something isn't up to date. So the openstreetmaps organisation might be happy at least :-)
