Poor city response to public services

For the past 3 months or more we are struggling to have a main water pipe in front of our house that burst, to be fixed by the city council. After numerous phone calls and emails we were told that the problem is a big problem and they will come back to fix it. The only thing replaced was our water meter. The water leak is become worse by the day. A sink hole is forming in the street. Water is leaking underground into our property. My paving was lifted and not replaced. Our water bill is very high and no one can tell is why. We are being sent mails to say the problem was fixed. It seems that no one really cares that so much water is being wasted. It also seems that i am not living in the right area to have the leak fixed asap. We have been living in this house since 1992 and always paid our rates and water bill on time. Yet this is how we are treated by tge city. During the water shortage period they begges us to report any watee leaks asap. Now they just dont care. We are frustrates and need a response asap. Otherwise our next step is to take this higher and also involve the ombudsman and newspapers.
