How do I get into contact w CAW?

TL DR: I need to ensure my water utility is set up. Can’t figure out what to do after requesting it online.

I moved to a new house recently and I am trying to set up water. We had a slight delay in the process so CAW wouldn’t let me transfer through my existing account. I requested starting a new service online through their (garbage) website. Got an email acknowledging it and that ‘someone will be in contact soon!’ But it’s been over a week. Their phone line says ‘new service requests can only be made online’ or dead ends at some point. I’m at a loss. Other utilities were easy compared to this.

My neighbor, who’s been battling them over a water leak, laughed at my story and told me to get a curb key to turn it back on if they come shut it off.

What do I do to prevent that issue from even happening?
