They were dealing with a property we were moving out of, passed on from another property manager. Must have told them a 1000 times to give us notice before they come for a viewing. Still came in unannounced. Update: What I didn't mention is that they actually walked in that time they came unannounced. Furthermore they have been calling and sending emails to get me to change my review with bribes, and to try and excuse what happened. They never actually apologised either. Crazy.
