I was screamed at when I called to get a copy of a form. I am just trying to comply with the rules regarding registering a tenant and Maggie screamed at me. I asked her what exactly she needed from me and she just shouted over and over "I already told you!!" I work with PMC companies all over the valley, and this level of unprofessionalism was pretty mind blowing. My client is elderly and unable to log in online and she just kept yelling at me to have him go online.
