My Gemini API usage spiked after Railway security incident

I stored Gemini API key as secrets in Railway, hosting platform.
They are all leaked and saw My Gemini API usage grew just around 0.3 USD to 800 USD per day. I deleted the keys from Google Cloud.

I hear sometimes Google consider remediation like refund but there is no contact form in Google Cloud. only this community forum link.

How can i deal?

for some people seeing this,

i resolved this via customer support chat. Not full compensation but generous amount of credits used for my next payment.

I could reached to them via Google Cloud billing support chat.

Firstly AI support agent talks but they cannot help at all so say “let this to human”, then human comes to chat.
