Why has my Doorbell Cam Pro uploaded 20 gigs in 3 weeks?

Why has my Doorbell Cam Pro uploaded 20 gigs in 3 weeks? It doesn’t even dectect motion and has never been rang? This is more bandwidth than any device in my house, including, 2 PC’s, three android tv boxes, one smartphone, one wyze and one amcrest cam. I would firewall them, but because they are cloud cams I won’t be able to view them.
