Aggresive Afhco SHLE management

I'm renting at South Hills Lifestyle Estate Block F. I've been here for 11months now and since day one. Everytime it would rain the hot water main switch would trip and the whole block will be without hot water. There are Block managers from Afhco who we have WhatsApp contact with but never read their WhatsApps and if they do they blue tick the messages and not even bother to respond. We have stayed a maximum of 2-3days bathing with kettle boiled water at anytime during the 11months of my stay here after a rain storm. The estate managers are very arrogant and rude and treat the tenants with little respect. Last week we were without hot water yet again because the rain season has started. individually in Block F we sent Peter and Bongani WhatsApps to inform them that we have no hot water and ofcourse there were no responses only blue ticks. At 13:00 I walked around the estate to find them and when I did... there was no apology nothing. Peter switched on the main switch for us. I asked him to not lock the main switch room so that we can lift it ourselves when it trips because they are non responsive and it's stressful to have to chase them around. On the evening of 23 Nov'19 it rained and the main switch tripped again. I bathed in kettle water that evening to go to work because Peter and Bongani had locked that room again and were not responding to phone calls or WhatsApps as usual. On 24 Nov. I came back home and left again for night shift work in the evening and there was still no hot water.. Today in the morning 25 Nov, I went to their office and found them in a meeting. I interrupted their meeting out of frustration because I'm tired to have to chase them around to get anything done. Again... I was met with an air of arrogance from the SHLE management team. Bongani told me that they were off during the weekend and all along telling me this with arrogance like it's none of their business that we spent 2days without hot water. It became an argument with Bongani being very aggressive and threatening. I'm a female tenant. I find it threatening that I'm treated with aggression when approaching them with problems. There's no intercom system in the estate. You approach them about this it's a problem . Our block laundry area is filthy. You approach them about this and for 1 week nothing gets done but WhatsApp messages have blue ticks. As a block we have resorted to connecting with an extension cord plugged in some doddgy way into the geyser plugs outside just so we can get hot water while waiting for response from Bongani and Peter. If u dont have an extension cord. You will bath with cold water. This is unacceptable. Can you please help!!
