IHS Property totally *********** agency who rips people off

I dont even know where to start but IHS Property management is the worst company to deal with. We had a problem with our water consumption being to high every month and they sent someone out to check for a leak in the unit but because there was no leak they told me to use water sparingly and they said i will need to pay the bill. I wasnt happy about this because how does your water consumption just increase when there is nobody at home during the day and weekends we hardly home and yet we paid more than all the tenants who has 5 to 6 adults in 1 unit and we only 2 adults, a teenager and a toddler . The past few months it skyrocketed and was 1st over R500 and then over R1000 and they now also realised there has to be a problem and sent a plumber. The plumbers checked the unit above us and confirmed that there was a leaking toilet and that we have been paying the water bill for our unit as well as the unit above us so I must take it up with the agency. The plumbers were here in July its already October and im still struggling to get this resolved. They now holding me accountable for the problem on their side and they feel I should pay a bill that is not mine because the tenants above us had already moved out because of issues with the agency. I keep sending emails to Monica who is the credit controller and she is totally ***********. I have proof of all my emails I sent to her and she says she will refer it and after that there is just no response. She ignores all my correspondence and in her mind its like to hell with the tenant l dont care and dont have to respond. I asked her for the details for their directors and still nothing she said she was off. I emailed her again this morning and no response as yet and l can guarentee you that l wint get any response from her
