I tried setting an appointment with a counselor but it says none are available?

I need to talk to a counselor because I need to figure out what to sign up for in winter registration but nothing is helping. My registration is on the 10th but I want to sign up for the correct classes and I’ve been trying to doing it for a week now. Any help?

Also any good counselor to talk to? I have trouble understanding and speaking to some of them.
