The problem is that you called the wrong place.
You called the city, which was neither involved nor consulted about housing the kids in an abandoned school. If you were rude, no wonder they hung up on you. You called the wrong office and talked to the wrong people.
See Post #28.
Call Grand Prairie ISD or the Dallas County Judge’s office if you want to complain to the people responsible.
What part of the saying, "I don't serve the government, the government serves me", don't you understand.
I guess you like government tyranny.
