Hey Rhythmscott,
Calling them wont do any better. The rep will just tell you they only answer questions regarding your issue via the message inquiry and they will get to your message soon. Unless you have an inside contact rep, most of the time its a hurry up & wait game. I’ve had tons of messages that I’ve sent within the last year. Some were answered quickly and some have still been unanswered.
You definitely can leave your legacy cues with ASCAP and start fresh with a new PRO. I just did the same thing this year. I’m getting new cues registered with my new PRO and my legacy cues are still with ASCAP collecting royalties.
Trust this info helps.
