Leaking water meter

Last year they came to change my water meter outside the yard, saying that I need the new one. In the month of May I have called them three times because it is now leaking. Everytime some guys come out to stop the leak and two days later it starts leaking again. They take three days to respond to the call, in that time the water is running down the street and adding to the bill. This only mean that those who come out don't know what the HELL they doing. This is ridiculous.
