Replace Greencard

i had a really bad experience with trying to replace my greencard. It was stolen and i need it to be replace in order to get a copy of my driver license. so we went to the office locations that was given to us online and i found out later on after two hour of time wasting around downtown atlanta that they had move and their online system need plenty of update and it is not helpful. when we finally got there to the right office i had to wait for two hour and it come to be they just give me a number ticket to wait again. they could've of just gave it to me but they are just jerks people who work there. They aren't helpful or professional. i want to maek a complaint on them. They was to my experience racist and don't want to help
