No water for 4 weeks , and Joburg Water does not give a ****

We have no water at our house in Rivonia Valley for the past 3 days (according to our Gardner, there has been no water for the past 4 weeks, but we were on leave so did not notice). We keep opening tickets with Joburg Water, and they keep telling us that there is no water because they are fixing a leak somewhere, and that the water will come back once the leak has been fixed. And they close our ticket, but the water never comes back. All our bills are paid on time, when will Joburg Water take the matter seriously?
