WATER METER LEAKAGE & INCORRECT BILLING

In August 2015 we had a water meter leakage outside our property and it was reported to the Municipal department. Three weeks has gone by and I reported the fault once again and my bill came with a huge amount on it. I called the City Of Cape Town again and they said the call was closed and the leak was repaired and nothing was done, the meter was still leaking. They then gave another reference number with the water department in Mitchells Plain number which I called. Almost a month that this thing has been leaking.they came to repair which I thought was repaired and not replaced. I then phoned them again for amendments and they said we had to take 3 readings before they can do any amendments, which we've doing but every time a big bill arrives as if nothing is being done to the account. I kept on paying R400 on my account not knowing what the proper amount was. I'm sitting with 10 reference numbers waiting on them to amend my account . I received an ITC letter of demand in this week to settle the account. I've forwarded to emails to the Mayor and ward councilor but no response. I went to the rates office to make arrangements but was requested to pay R2500 deposit on R3500 outstand
