It happened the same to me. However, they sent me a letter that I missed the scheduled FP. I just dropped by and showed them the letter. But those guys asked me to make appiontment with Infopass. Fortunately, I brought my laptop and made an apponintment right away at the same day. Otherwise, I will spend another day for trvel back. After talk with Infopass, I got my FP. So, I suggest you bring all your document and see the Infopass (make an appointment before you go). Good luck.
