Disappointing lack of action from COCT Water department

I have had a leak on my property for 2 months. From first logging it on 5 February to now. I have tried all their escalation methods advised, logging, phoning the call centre, including writing to the mayor's email address and the problem has not been attended to. I have had numerous sms' advising that its escalated to the depot and the Branch Manager but no action. They actually sent a team out last week that got the brief wrong despite what the logged fault says? I can't get a water rebate since they first need to fix this, and they reminded me to pay my bill.?
