I made an appointment online. But I wanted to confirm it and they don't answer the phone. Is there another way to confirm?

I already have 3 weeks that I went to the appointment and they do not send me my passport

Write to the Messenger of the official website of the consulate, they answer by that means.

I think they will not answer the phone, I will do the same, but if you have already made the appointment, you do not need to confirm it, just take the printed confirmation that the site gave you at the time of making it, you will not have problems if you take it and also they are very attentive there I had a good experience, very good attention.
