I’ve been using AppEngine for years and really like it. Had an interesting billing issue recently.

I enabled a task queue to run a longer running task in the background but I didn’t realize there’s a default to retry failed tasks indefinitely. This started slowly increasing my front end instance hours (and my bill). A few hundred bucks later I figured it out and specified a retry attempts limit.

I had a similar issue and contacted them for a refund. It worked out fine and they refunded the full amount. It might be worth giving it a shot!
