Music registration with PRO’s – Everything Else (Music related) Forum

Not sure if this is the right place. If not, let me know. Kick me in the right direction.

I register my songs with Songtrust. They submit my music worldwide to the PRO’s, like ASCAP. But how do I figure out if this really happens. I have my doubts, because Songtrust is very slow with this. Many of my songs do not show up at ASCAP after many months. I know that because I am an ASCAP member.
Their support is not very good, to say it nice. After 4-5 weeks I get not very helpful answers.

So how do I know if my song X is registered with PRO Y in the country Z.
