Technicians never see a customer's phone number.

A tech takes a job from the website and gets a time, a location, and a description of what's broken. They don't get your phone number. If something goes wrong, the website calls the tech, not the other way around. You stay private.

It's a small thing that matters. You don't have to worry about a tech holding onto your number after the job is done, or calling you at odd hours, or selling it to someone else. The website keeps that boundary clean.
