Useless disregard for flooding problem (Murano Bryanston)

I am horrified by how a company, called "Property Specialists" do not offer much in the way of anything special. Murano - a beautiful, upmarket residential estate in Bryanston, Johannesburg was built by Summercon, with no down-pipes in the single units. As a result, water coming off the roof, cascades onto the patio flooding it and causing continuous damage to furniture and the tiles. I have requested for the problem to be addressed 6 months ago and keep being shafted; obviously single-unit owners are not seen as valuable members or important enough levy-paying clients. I would NOT recommend using them, nor Easy-Living Agents either as between the two of them, no one can make a decision or at least even try to resolve the problem.
