The worst place ever, not helpful at all, my first...

The worst place ever, not helpful at all, my first time trying to get a visa, had all my paperwork shots, American passport, flight info, pics. Just going on vacation. Was not helpful. Now going to apply again online. If that dont work. I will cancel my flight. Why are they here in America when they are not helpful to Americans, very rude and nasty. Plus wanted me to go to some guy to get my visa, said he charges 200 hundred dollars plus processing free. Scamming.
