incorrect listing

On Local corporation my listing had the wrong phone number, so I went on my account and edited it.

Simple. Well, I check in weeks later, and local corporation and all the subsidieries still have the wrong information!!

I called their toll free phone number but it went straight to a message box, and I emailed them but didn't get anything back. What do I do?
I want to say I have about 25 wrong listings due to this.
