Models, I need your advice

Currently got signed to an Agency however I no longer want to be in it. It is an Open-casting agency which means that they post jobs on a group-chat and the only way to get it is to say you are interested in the comments. They will not pitch you personally. You are also expected to change your portfolio yourself, too.

I want to go to a mother agency but I am unsure if I have the look.

I have become a bit frustrated because they promised 1:1 management, yet when I asked they completely side stepped the question and just promised me there would be a group meeting soon.

Should I just wait it out and see? Because I have a decent portfolio right now but am frustrated with the methods, there are around 600 people under the agency so it feels like booking a job is impossible.
