Absolute zero rating. I've had raw sewage backing up into my kitchen for six straight days and RHP are yet to address the issue which affects four other properties in the block and is spilling out into the communal area from a first floor walkway. Continual no shows from their maintenance crew, empty promises and hollow sympathy from their customer service department. Absolutely incompetent. Don't go near them.
