I applied online to renew my passport, but didn't get an interview date, I was told to contact the office to schedule an interview. I called there multiple times, no-one answered. I decided to go down to the office in New York. When I got there, I was told to write my name, number and reference number down and someone would give me a call back between 11 and 2pm the same day. I didn't receive any phone call and still yet to receive an interview date.
