Honestly, due to Covid-19, they are booked for up to two weeks , so if you need it within a week, it's impossible.
Call again. Try the options where they asked you if you had an appointment even if you don't yet just get a hold of some one on the phone. They are going to ask if you have a proof of travel within 14 days o 72 hours if is an emergency. And they are going to ask you for a document that shows A life or death situation. As someone is dying or really sick or a funeral. You have to have it in english. Maybe they are full on appointments but they will call you and find you a spot. Just try again try to speak with someone.
