Just bought a brand new house and called to set up my account they said they didn't have a letter in yet from the builder but the water will still be on until they receive the letter. That was Friday, today is Monday and I come home to no water and it's shut off I tried calling and they are already closed. The women who answered the emergency water line said "sorry call back tomorrow that's a customer service issue not my problem." Are you kidding me?! No water and no warning just a drive by turn off the water no note on the door nothing!
