Incorrect billing by City of Joburg

I’ve been trying to get right people since last week after receiving the statement reflecting that I owe R65, 338.50. I believe that the amount is incorrect as my account is up to date. I phoned your call centre over the weekend and the consultant namely Leeto Mogale told me that the amount is for the water usage from February to date, the version that I dispute. The statement shows end reading of 2,752.000 and my meter is at the moment sitting at 2,101.00, there are 3-meter boxes on my pavement and the one next to my meter is at 2, 784.00 which is higher to the figure reflecting on my statement and meter, and which is closer to the figure reflecting on my statement. This tells me that whoever took readings possibly took from the wrong meter.
