City of Johannesburg is the worst !

What a terrible experience I have had to face for the past 2/3 years , I was billed over R60000 in one month on a residential property for water and lights . I have escalated the matter countless times to the ombudsman which made its recommendations but they were never actioned at all . City of Johannesburg is the worst of the worst . When you physically go to their offices to lay a complaint I was told to go home and call them instead?? Does that make any sense why could they not assist me at their offices . When you call them they say they will send a technician 21 days is the TAT I have been waiting for over a year !! My bill keeps pulling up and no one wants to help me . The service is terrible , their communication is non existent. At this point I do not know what to do
