Average warranty response time

Hey!

I had to contact warranty because of a long standing problem with my cpu. Its critical for my work, so i just wanted to know the average response time for these things. I submitted the form and got a couple automated responses, but most pages related to support seem broken or no longer operational. By the way i live in Brazil, so i know the response time may vary. I had to stop all my work so I'm a bit impatient about this. Thanks!
