Black Katz basically ruined my life during the time I rented with them. Rude, inefficient and dishonest. Every maintenance enquiry was put aside for as long as possible, including a mice infestation and a cracked wall, leaving my living room exposed to the outside. During the same period, they increased the rent way above inflation, and told me that I was "demanding" and "out of touch with reality" when I questioned their actions/lack of action. Would not owe it to my worst enemy to stay in one of the properties!
What agent could do to change your mind?
Nothing - apart from staying far away from me.
