Property office put my 6 month old son at risk by telling me it was safe to take him in because the apartment was not treated. It was treated. I found the paper stating so when I was cleaning. Dangerous pest control chemicals that you are supposed to stay away from for 6 hours and they told me that it was safe to take my son in there. Then when I try to call corporate I can not reach them. Crappy!
