A tech never sees your phone number.

When you post a repair job on a website where local service providers bid on work, the provider sees what needs fixing. He does not see your name, your phone number, or where you live. The website operator calls you first to confirm the provider is actually coming.

This matters because you control when a stranger gets your contact info. A provider can offer to do the job, sure. But he only learns how to reach you once the website has already called you with his time and confirmed you are home. If you say no, your number stays private.

It is a small shift, but it changes the whole dynamic. You are not worried about unsolicited calls. The provider is not sitting on your address. The website is the gatekeeper, which is how it should be.
