Consulate problems

Hey, I'm in Florida my father and I are Brazilian dual citizens. I have my Brazilian passport valid but his is out of date. I can't seem to get any help from the consulate on the phone or by email, and I haven't had any luck creating an account for him because the website sucks. It keeps going to 404, or not sending me the validation code. They say I can't make an appointment for the consulate otherwise and I can't walk in. Does anyone have any advice?
