does my IT person know about FTP?

[space-time]

I had to download a file from an FTP server for work. I could not connect form work, I tried Internet Explorer, FileZilla, no joy. I asked IT if they block FTP; instead of Yes or No, IT Person replied that I had to use FileZilla (which I already tried) and I had to ask the vendor (who runs the FTP server) to use FileZilla on their side as well. WHAT? why would that make a difference? Isn't FileZilla a Client, what does that have to do with a server? I came home, downloaded the file, will put on USB stick and take to work. Just a 24 hour delay because they block FTP.
