Someone complained about a person who fills out Adsense forums and verifies them on mobile.

Today, I received a complaint about the advertisements on my website. Someone visited my site, filled out a form, and was charged over 60 units on their invoice. They confirmed the code sent from their mobile. I don't understand how this is related to AdSense advertising. Can someone who knows about this please write to me? Thank you.
