Divshot, acquired and shut down a year ago, just billed me

I was a customer of Divshot until they were acquired by Firebase last year. Imagine my surprise when I just received a Stripe email receipt from them. They haven't charged me since last year, I wonder if their billing system erroneously set to continue charging me but on an annual basis.

Has this happened to anyone else? I've pinged a note to their support email, will update here once I hear back from them.

Update: Firebase Support just confirmed that it's an issue and that I'll be issued a refund soon.
