Terrible service from the agents even after a monthly admin fee of R100

After giving us a bill of R4000 for water from june 2016 in september of this year, we worked out an arrangement to pay off the ammount over 4 months for their error of not providing us with water bills for a year and then threatening to negatively affect my credit record. This was apparently not good enough and after 3 months of paying an extra R1000 a month for the bill, they still negatively marked my credit record. They havent given us a signed lease from the landlord for this year and there has been 3 diffenrent maintainance personal dealing with me over the past 6 months, none of them had any clie of the outstanding maintainance from 3 years ago that is still outstanding. I will never rent through them ever again and i will make sure that everyone i know is aware of their terrible service.
