Correct way to stop fetchmail

[Roger Price]

I would like to stop fetchmail on Debian 11.  I tried command systemctl stop 
fetchmail and system status fetchmail reported

 ● fetchmail.service - LSB: init-Script for system wide fetchmail daemon

It's dead, but still fetching mail! I tried

 root@titan ~ /etc/init.d/fetchmail --quit
 Not starting fetchmail daemon, disabled via /etc/default/fetchmail.

but fetchmail goes on fetching mail.  What is the correct way of stopping 
fetchmail?
