4Max properties **** their clients

Hi, I have a problem with 4Max properties. At first I reported an issue of buying an R2000 electricity prepaid per month just for lights and geyser and cooking 3 times a week and it was not sorted and I told myself I’ll wait till month end April to move out. Den from month end January they started to bill me abnormally in water and sewage. They started by sending me a bill which I normally paid and 2 days after they send me the other one which have water and sewage of more than R1000. I asked them why and they promised to fix it and never came back to me so I decided to pay the first money they invoiced me before sending the other one. Month end February they billed me water and sewage of more than R2000 and carried out the other money from last month which dey promised to fix. I tried to call them and the urgent who helped me by the name of Nita was very rude and dropped my call wen I ask her about where is their office. No one want to take the blame from 4Max and they just blame everything on the their account office which is they can’t even tell u where they are. I need help coz now I feel like they are trying to **** me and it is their way of trying to keep my deposit since I don’t renew the contract with them.
