Sub-standard service from black female owned co.

In Dec 2015 I contacted Zamapho Property Management (ZPM) to assist me with finding tenants for my townhouse. I came across their details on Property24 thought it would be a good idea to support a black owned company, which unfortunately turned out to be a nightmare. They didn't waste time in finding me 2 tenants. However when I received the lease agreement it had at least 8 errors, ranging from incorrect personal details, to contradictory sub clauses. 23 days after moving in, neighbours in the complex alerted me that there were @ least 10 men staying in my unit (2 bed 1 bath) - ZPM had led me to believe that two people were staying there. Upon doing my own investigation, I found my place in a vandalised and messy state. Even after ZMP saw the state of the house, they told me I could not evict the tenants. They promised to do weekly inspections, and to date, I have not received feedback, unless I ask for it. When I questioned why I should be begging for feedback for services I have paid for, The owner of ZPM had the nerve to tell me that she is doing me a favour. The tenants should move out 2moro, but ZPM has not even bothered to facilitate the process for me to get my keys
