City of Cape town bad service delivery

I dont know if i am using the right playform to lay a complain against city of cape town municipality. I have tried every avenue but to no success. My husband i moved into our house in 2017 and has been complaining about our water meter that has been faulty. Its 2021 already and still nothing. We have been to every office of city of cape town. All we get is reference numbers claiming the busy investigating. Our water has been estimated ever since we moved into our property and when we laid a complain , we were told just to pay the minimum amount seeing that is not our right water reading. We were told that the account would be placed on hold and would not accrue any further till the matter has been resolved. In the year 2019 my husband received a letter from head office stating that the needs to make arrangement on payment or they will deduct everything from his bonus as he is a city of cape town employee. We went to head office to try to make arrangement, but the staff was rude and illiterate they couldnt even assist us. Bear in mind no arrangement has been made that money can be deducted from his salary and then november came when the city receives their bonuses and they deducted 50% of his bonus. Ever since that they are deducting money of his account every month. Yet nothing has been done about the faulty water meter. City of cape town is the worst on service delivery to our law abiding rates and tax payers. However informal settlements gets unlimited water free of charge. I am disgusted by the service i received from you guys. I would like to know what i can do to get assistance from the city of cape municipality to fix my broken water meter.
