City of Capetown poor and no customer service

I have been receiving extremely high water bills, average R20000 per month since Feb 2018. Made numerous visits, and countless calls to the city to enquire this. All I could get out of them was they are investigating and will get back to me, which no response is received. I had a private plumber, check for leaks and found none. In April I requested the City to test the meter, as I suspected that to be the problem, which I had to pay them to remove and test. Took them 2 months to test the meter, while the bill was escalating monthly. Finally end of June, it was found that the meter was faulty. To date I'm still awaiting my account to be credited. I'm now sitting with a water bill of R125,640 and once again numerous calls and visits to the City of Capetown, not one individual can give me an answer of when will this be resolved. Nobody from the City of Capetown gives customers feedback, numerous promises made but not kept by there staff members.
