I need to head out for lunch, but I wanted to ask a few more questions...
Are you sure they intended for you to connect to them via FTP? They might not have an FTP server.
Are you the first person they've had connect to them via FTP? Perhaps something on their end. Such as they set up the account wrong, or they have port 21 blocked. It's also possible they didn't have their FTP server running when you attempted to connect.
I'll be back in an hour to help.
