I finally got a pin after years and years. I initially done what everyone had said, go online and create itineries, save this and that, etc. Still didn't get one. So I went and opened a new email address and finally (it took about a month) got a pin. Unfortunately it was for a visit before 8/14 and I plan to go in sept. So anyone who is still trying to get a pin, open up a complete new email address and see if you get one.
