Is admob ads disabled?

Question

Google AdMob

Hello, yesterday I received this message:
We have detected a policy violation in one or more of your applications and have disabled ads.
The application in which the display was disabled does not belong to me! It is written that it was deleted in 2019, my account is only a month old, before this message I wanted to publish the application on google play, I downloaded the apk and the inscription came out: the package name is already tested in Google play, But my admob account and Google play are different,
What is it! ?
